-  and follows the naming convention: em_usbd<em>nnn</em>.c/h.

-@n @section usb_device_intro Introduction
-
-  The USB device protocol stack provides an API which makes it possible to
-  create USB devices with a minimum of effort. The device stack supports control,
-  bulk and interrupt transfers.
-
-  The stack is highly configurable to suit various needs, it does also contain
-  useful debugging features together with several demonstration projects to
-  get you started fast.
-
-  We recommend that you read through this documentation, then proceed to build
-  and test a few example projects before you start designing your own device.
-
-@n @section usb_device_api The device stack API
-
-  This section contains brief descriptions of the functions in the API. You will
-  find detailed information on input and output parameters and return values by
-  clicking on the hyperlinked function names. It is also a good idea to study
-  the code in the USB demonstration projects.
-
-  Your application code must include one header file: @em em_usb.h.
-
-  All functions defined in the API can be called from within interrupt handlers.
-
-  The USB stack use a hardware timer to keep track of time. TIMER0 is the
-  default choice, refer to @ref usb_device_conf for other possibilities.
-  Your application must not use the selected timer.
-
-  <b>Pitfalls:</b>@n
-    The USB peripheral will fill your receive buffers in quantities of WORD's
-    (4 bytes). Transmit and receive buffers must be WORD aligned, in
-    addition when allocating storage for receive buffers, round size up to
-    next WORD boundary. If it is possible that the host will send more data
-    than your device expects, round buffer size up to the next multiple of
-    maxpacket size for the relevant endpoint to avoid data corruption.
-
-    Transmit buffers passed to @htmlonly USBD_Write() @endhtmlonly must be
-    statically allocated because @htmlonly USBD_Write() @endhtmlonly only
-    initiates the transfer. When the host decide to actually perform the
-    transfer, your data must be available.
-
-  @n @ref USBD_Init() @n
-    This function is called to register your device and all its properties with
-    the device stack. The application must fill in a @ref USBD_Init_TypeDef
-    structure prior to calling. Refer to @ref DeviceInitCallbacks for the
-    optional callback functions defined within this structure. When this
-    function has been called your device is ready to be enumerated by the USB
-    host.
-
-  @ref USBD_Read(), @ref USBD_Write() @n
-    These functions initiate data transfers.
-    @n @htmlonly USBD_Read() @endhtmlonly initiate a transfer of data @em
-    from host @em to device (an @em OUT transfer in USB terminology).
-    @n @htmlonly USBD_Write() @endhtmlonly initiate a transfer of data @em from
-    device @em to host (an @em IN transfer).
-
-    When the USB host actually performs the transfer, your application will be
-    notified by means of a callback function which you provide (optionally).
-    Refer to @ref TransferCallback for details of the callback functionality.
-
-  @ref USBD_AbortTransfer(), @ref USBD_AbortAllTransfers() @n
-    These functions terminate transfers that are initiated, but has not yet
-    taken place. If a transfer is initiated with @htmlonly USBD_Read()
-    or USBD_Write(), @endhtmlonly but the USB host never actually peform
-    the transfers, these functions will deactivate the transfer setup to make
-    the USB device endpoint hardware ready for new (and potentially) different
-    transfers.
-
-  @ref USBD_Connect(), @ref USBD_Disconnect() @n
-    These functions turns the data-line (D+ or D-) pullup on or off. They can be
-    used to force reenumeration. It's good practice to delay at least one second
-    between @htmlonly USBD_Disconnect() and USBD_Connect() @endhtmlonly
-    to allow the USB host to unload the currently active device driver.
-
-  @ref USBD_EpIsBusy() @n
-    Check if an endpoint is busy.
-
-  @ref USBD_StallEp(), @ref USBD_UnStallEp() @n
-    These functions stalls or un-stalls an endpoint. This functionality may not
-    be needed by your application, but the USB device stack use them in response
-    to standard setup commands SET_FEATURE and CLEAR_FEATURE. They may be useful
-    when implementing some USB classes, e.g. a mass storage device use them
-    extensively.
-
-  @ref USBD_RemoteWakeup() @n
-    Used in SUSPENDED state (see @ref USB_Status_TypeDef) to signal resume to
-    host. It's the applications responsibility to adhere to the USB standard
-    which states that a device can not signal resume before it has been
-    SUSPENDED for at least 5 ms. The function will also check the configuration
-    descriptor defined by the application to see if it is legal for the device
-    to signal resume.
-
-  @ref USBD_GetUsbState() @n
-    Returns the device USB state (see @ref USBD_State_TypeDef). Refer to
-    Figure 9-1. "Device State Diagram" in the USB revision 2.0 specification.
-
-  @ref USBD_GetUsbStateName() @n
-    Returns a text string naming a given USB device state.
-
-  @ref USBD_SafeToEnterEM2() @n
-    Check if it is ok to enter energy mode EM2. Refer to the
-    @ref usb_device_powersave section for more information.
-
-  @n @anchor TransferCallback <b>The transfer complete callback function:</b> @n
-    @n USB_XferCompleteCb_TypeDef() is called when a transfer completes. It is
-    called with three parameters, the status of the transfer, the number of
-    bytes transferred and the number of bytes remaining. It may not always be
-    needed to have a callback on transfer completion, but you should keep in
-    mind that a transfer may be aborted when you least expect it. A transfer
-    will be aborted if host stalls the endpoint, if host resets your device, if
-    host unconfigures your device or if you unplug your device cable and the
-    device is selfpowered.
-    @htmlonly USB_XferCompleteCb_TypeDef() @endhtmlonly is also called if your
-    application use @htmlonly USBD_AbortTransfer() or USBD_AbortAllTransfers()
-    @endhtmlonly calls.
-    @note This callback is called from within an interrupt handler with
-          interrupts disabled.
-
-  @n @anchor DeviceInitCallbacks <b>Optional callbacks passed to the stack via
-    the @ref USBD_Init() function:</b> @n
-    @n These callbacks are all optional, and it is up to the application
-    programmer to decide if the application needs the functionality they
-    provide.
-    @note These callbacks are all called from within an interrupt handler
-          with interrupts disabled.
-
-  USBD_UsbResetCb_TypeDef() is called each time reset signalling is sensed on
-    the USB wire.
-
-  @n USBD_SofIntCb_TypeDef() is called with framenumber as a parameter on
-    each SOF interrupt.
-
-  @n USBD_DeviceStateChangeCb_TypeDef() is called whenever the device state
-    change. Useful for detecting e.g. SUSPENDED state change in order to reduce
-    current consumption of buspowered devices. The USB HID keyboard example
-    project has a good example on how to use this callback.
-
-  @n USBD_IsSelfPoweredCb_TypeDef() is called by the device stack when host
-    queries the device with a standard setup GET_STATUS command to check if the
-    device is currently selfpowered or buspowered. This feature is only
-    applicable on selfpowered devices which also works when only buspower is
-    available.
-
-  @n USBD_SetupCmdCb_TypeDef() is called each time a setup command is
-    received from host. Use this callback to override or extend the default
-    handling of standard setup commands, and to implement class or vendor
-    specific setup commands. The USB HID keyboard example project has a good
-    example on how to use this callback.
-
-  @n <b>Utility functions:</b> @n
-    @n    USB_PUTCHAR() Transmit a single char on the debug serial port.
-    @n @n USB_PUTS() Transmit a zero terminated string on the debug serial port.
-    @n @n USB_PRINTF() Transmit "printf" formated data on the debug serial port.
-    @n @n USB_GetErrorMsgString() Return an error message string for a given
-          error code.
-    @n @n USB_PrintErrorMsgString() Format and print a text string given an
-          error code, prepends an optional user supplied leader string.
-    @n @n USBTIMER_DelayMs() Active wait millisecond delay function. Can also be
-          used inside interrupt handlers.
-    @n @n USBTIMER_DelayUs() Active wait microsecond delay function. Can also be
-          used inside interrupt handlers.
-    @n @n USBTIMER_Init() Initialize the timer system. Called by @htmlonly
-          USBD_Init(), @endhtmlonly but your application must call it again to
-          reinitialize whenever you change the HFPERCLK frequency.
-    @n @n USBTIMER_Start() Start a timer. You can configure the USB device stack
-          to provide any number of timers. The timers have 1 ms resolution, your

-  @n You are strongly encouraged to start application development with DEBUG_USB_API
-  turned on. When DEBUG_USB_API is turned on and USER_PUTCHAR is defined, useful
-  debugging information will be output on the development kit serial port.
-  Compiling with the DEBUG_EFM_USER flag will also enable all asserts

-
-  You application must include @em retargetserial.c if DEBUG_USB_API is defined

-  These files reside in the @em drivers
-  directory in the software package for your development board. Refer to
-  @ref usb_device_powersave for energy-saving mode configurations.
-
-@n @section usb_device_powersave Energy-saving modes
-
-  The device stack provides two energy saving levels. The first level is to
-  set the USB peripheral in energy saving mode, the next level is to enter
-  Energy Mode 2 (EM2). These energy saving modes can be applied when the device
-  is suspended by the USB host, or when when the device is not connected to a
-  USB host.
-  In addition to this an application can use energy modes EM1 and EM2. There
-  are no restrictions on when EM1 can be entered, EM2 can only be entered
-  when the USB device is suspended or detached from host.
-
-  Energy-saving modes are selected with a \#define in @em usbconfig.h, default
-  selection is to not use any energy saving modes.@n @n
-  @verbatim
-#define USB_PWRSAVE_MODE (USB_PWRSAVE_MODE_ONSUSPEND | USB_PWRSAVE_MODE_ENTEREM2)@endverbatim
-
-  There are three flags available, the flags can be or'ed together as shown above.
-
-  <b>\#define USB_PWRSAVE_MODE_ONSUSPEND</b>@n Set USB peripheral in low power
-  mode on suspend.
-
-  <b>\#define USB_PWRSAVE_MODE_ONVBUSOFF</b>@n Set USB peripheral in low power
-  mode when not attached to a host. This mode assumes that the internal voltage
-  regulator is used and that the VREGI pin of the chip is connected to VBUS.
-  This option can not be used with bus-powered devices.
-
-  <b>\#define USB_PWRSAVE_MODE_ENTEREM2</b>@n Enter EM2 when USB peripheral is
-  in low power mode.
-
-  When the USB peripheral is set in low power mode, it must be clocked by a 32kHz
-  clock. Both LFXO and LFRCO can be used, but only LFXO guarantee USB specification
-  compliance. Selection is done with a \#define in @em usbconfig.h.@n @n
-  @verbatim
-#define USB_USBC_32kHz_CLK   USB_USBC_32kHz_CLK_LFXO @endverbatim
-  Two flags are available, <b>USB_USBC_32kHz_CLK_LFXO</b> and
-  <b>USB_USBC_32kHz_CLK_LFRCO</b>. <b>USB_USBC_32kHz_CLK_LFXO</b> is selected
-  by default.
-
-  The USB HID keyboard and Mass Storage device example projects demonstrate
-  different energy-saving modes.
-
-  <b>Example 1:</b>
-  Leave all energy saving to the stack, the device enters EM2 on suspend and
-  when detached from host. @n
-  @verbatim
-In usbconfig.h:
-
-#define USB_PWRSAVE_MODE (USB_PWRSAVE_MODE_ONSUSPEND | USB_PWRSAVE_MODE_ONVBUSOFF | USB_PWRSAVE_MODE_ENTEREM2)
-  @endverbatim
-
-  @n <b>Example 2:</b>
-  Let the stack control energy saving in the USB periheral but let your
-  application control energy modes EM1 and EM2. @n
-  @verbatim
-In usbconfig.h:
-
-#define USB_PWRSAVE_MODE (USB_PWRSAVE_MODE_ONSUSPEND | USB_PWRSAVE_MODE_ONVBUSOFF)

+@n @section usb_device_intro Introduction
+
+  The USB device protocol stack provides an API which makes it possible to
+  create USB devices with a minimum of effort. The device stack supports control,
+  bulk and interrupt transfers.
+
+  The stack is highly configurable to suit various needs, it does also contain
+  useful debugging features together with several demonstration projects to
+  get you started fast.
+
+  We recommend that you read through this documentation, then proceed to build
+  and test a few example projects before you start designing your own device.
+
+@n @section usb_device_api The device stack API
+
+  This section contains brief descriptions of the functions in the API. You will
+  find detailed information on input and output parameters and return values by
+  clicking on the hyperlinked function names. It is also a good idea to study
+  the code in the USB demonstration projects.
+
+  Your application code must include one header file: @em em_usb.h.
+
+  All functions defined in the API can be called from within interrupt handlers.
+
+  The USB stack use a hardware timer to keep track of time. TIMER0 is the
+  default choice, refer to @ref usb_device_conf for other possibilities.
+  Your application must not use the selected timer.
+
+  <b>Pitfalls:</b>@n
+    The USB peripheral will fill your receive buffers in quantities of WORD's
+    (4 bytes). Transmit and receive buffers must be WORD aligned, in
+    addition when allocating storage for receive buffers, round size up to
+    next WORD boundary. If it is possible that the host will send more data
+    than your device expects, round buffer size up to the next multiple of
+    maxpacket size for the relevant endpoint to avoid data corruption.
+
+    Transmit buffers passed to @htmlonly USBD_Write() @endhtmlonly must be
+    statically allocated because @htmlonly USBD_Write() @endhtmlonly only
+    initiates the transfer. When the host decide to actually perform the
+    transfer, your data must be available.
+
+  @n @ref USBD_Init() @n
+    This function is called to register your device and all its properties with
+    the device stack. The application must fill in a @ref USBD_Init_TypeDef
+    structure prior to calling. Refer to @ref DeviceInitCallbacks for the
+    optional callback functions defined within this structure. When this
+    function has been called your device is ready to be enumerated by the USB
+    host.
+
+  @ref USBD_Read(), @ref USBD_Write() @n
+    These functions initiate data transfers.
+    @n @htmlonly USBD_Read() @endhtmlonly initiate a transfer of data @em
+    from host @em to device (an @em OUT transfer in USB terminology).
+    @n @htmlonly USBD_Write() @endhtmlonly initiate a transfer of data @em from
+    device @em to host (an @em IN transfer).
+
+    When the USB host actually performs the transfer, your application will be
+    notified by means of a callback function which you provide (optionally).
+    Refer to @ref TransferCallback for details of the callback functionality.
+
+  @ref USBD_AbortTransfer(), @ref USBD_AbortAllTransfers() @n
+    These functions terminate transfers that are initiated, but has not yet
+    taken place. If a transfer is initiated with @htmlonly USBD_Read()
+    or USBD_Write(), @endhtmlonly but the USB host never actually peform
+    the transfers, these functions will deactivate the transfer setup to make
+    the USB device endpoint hardware ready for new (and potentially) different
+    transfers.
+
+  @ref USBD_Connect(), @ref USBD_Disconnect() @n
+    These functions turns the data-line (D+ or D-) pullup on or off. They can be
+    used to force reenumeration. It's good practice to delay at least one second
+    between @htmlonly USBD_Disconnect() and USBD_Connect() @endhtmlonly
+    to allow the USB host to unload the currently active device driver.
+
+  @ref USBD_EpIsBusy() @n
+    Check if an endpoint is busy.
+
+  @ref USBD_StallEp(), @ref USBD_UnStallEp() @n
+    These functions stalls or un-stalls an endpoint. This functionality may not
+    be needed by your application, but the USB device stack use them in response
+    to standard setup commands SET_FEATURE and CLEAR_FEATURE. They may be useful
+    when implementing some USB classes, e.g. a mass storage device use them
+    extensively.
+
+  @ref USBD_RemoteWakeup() @n
+    Used in SUSPENDED state (see @ref USB_Status_TypeDef) to signal resume to
+    host. It's the applications responsibility to adhere to the USB standard
+    which states that a device can not signal resume before it has been
+    SUSPENDED for at least 5 ms. The function will also check the configuration
+    descriptor defined by the application to see if it is legal for the device
+    to signal resume.
+
+  @ref USBD_GetUsbState() @n
+    Returns the device USB state (see @ref USBD_State_TypeDef). Refer to
+    Figure 9-1. "Device State Diagram" in the USB revision 2.0 specification.
+
+  @ref USBD_GetUsbStateName() @n
+    Returns a text string naming a given USB device state.
+
+  @ref USBD_SafeToEnterEM2() @n
+    Check if it is ok to enter energy mode EM2. Refer to the
+    @ref usb_device_powersave section for more information.
+
+  @n @anchor TransferCallback <b>The transfer complete callback function:</b> @n
+    @n USB_XferCompleteCb_TypeDef() is called when a transfer completes. It is
+    called with three parameters, the status of the transfer, the number of
+    bytes transferred and the number of bytes remaining. It may not always be
+    needed to have a callback on transfer completion, but you should keep in
+    mind that a transfer may be aborted when you least expect it. A transfer
+    will be aborted if host stalls the endpoint, if host resets your device, if
+    host unconfigures your device or if you unplug your device cable and the
+    device is selfpowered.
+    @htmlonly USB_XferCompleteCb_TypeDef() @endhtmlonly is also called if your
+    application use @htmlonly USBD_AbortTransfer() or USBD_AbortAllTransfers()
+    @endhtmlonly calls.
+    @note This callback is called from within an interrupt handler with
+          interrupts disabled.
+
+  @n @anchor DeviceInitCallbacks <b>Optional callbacks passed to the stack via
+    the @ref USBD_Init() function:</b> @n
+    @n These callbacks are all optional, and it is up to the application
+    programmer to decide if the application needs the functionality they
+    provide.
+    @note These callbacks are all called from within an interrupt handler
+          with interrupts disabled.
+
+  USBD_UsbResetCb_TypeDef() is called each time reset signalling is sensed on
+    the USB wire.
+
+  @n USBD_SofIntCb_TypeDef() is called with framenumber as a parameter on
+    each SOF interrupt.
+
+  @n USBD_DeviceStateChangeCb_TypeDef() is called whenever the device state
+    change. Useful for detecting e.g. SUSPENDED state change in order to reduce
+    current consumption of buspowered devices. The USB HID keyboard example
+    project has a good example on how to use this callback.
+
+  @n USBD_IsSelfPoweredCb_TypeDef() is called by the device stack when host
+    queries the device with a standard setup GET_STATUS command to check if the
+    device is currently selfpowered or buspowered. This feature is only
+    applicable on selfpowered devices which also works when only buspower is
+    available.
+
+  @n USBD_SetupCmdCb_TypeDef() is called each time a setup command is
+    received from host. Use this callback to override or extend the default
+    handling of standard setup commands, and to implement class or vendor
+    specific setup commands. The USB HID keyboard example project has a good
+    example on how to use this callback.
+
+  @n <b>Utility functions:</b> @n
+    @n    USB_PUTCHAR() Transmit a single char on the debug serial port.
+    @n @n USB_PUTS() Transmit a zero terminated string on the debug serial port.
+    @n @n USB_PRINTF() Transmit "printf" formated data on the debug serial port.
+    @n @n USB_GetErrorMsgString() Return an error message string for a given
+          error code.
+    @n @n USB_PrintErrorMsgString() Format and print a text string given an
+          error code, prepends an optional user supplied leader string.
+    @n @n USBTIMER_DelayMs() Active wait millisecond delay function. Can also be
+          used inside interrupt handlers.
+    @n @n USBTIMER_DelayUs() Active wait microsecond delay function. Can also be
+          used inside interrupt handlers.
+    @n @n USBTIMER_Init() Initialize the timer system. Called by @htmlonly
+          USBD_Init(), @endhtmlonly but your application must call it again to
+          reinitialize whenever you change the HFPERCLK frequency.
+    @n @n USBTIMER_Start() Start a timer. You can configure the USB device stack
+          to provide any number of timers. The timers have 1 ms resolution, your
+          application is notified of timeout by means of a callback.
+    @n @n USBTIMER_Stop() Stop a timer.
+
+@n @section usb_device_conf Configuring the device stack
+
+  Your application must provide a header file named @em usbconfig.h. This file

+  @n You are strongly encouraged to start application development with DEBUG_USB_API
+  turned on. When DEBUG_USB_API is turned on and USER_PUTCHAR is defined, useful

+  These files reside in the @em drivers
+  directory in the software package for your development board. Refer to
+  @ref usb_device_powersave for energy-saving mode configurations.
+
+@n @section usb_device_powersave Energy-saving modes
+
+  The device stack provides two energy saving levels. The first level is to
+  set the USB peripheral in energy saving mode, the next level is to enter
+  Energy Mode 2 (EM2). These energy saving modes can be applied when the device
+  is suspended by the USB host, or when when the device is not connected to a
+  USB host.
+  In addition to this an application can use energy modes EM1 and EM2. There
+  are no restrictions on when EM1 can be entered, EM2 can only be entered
+  when the USB device is suspended or detached from host.
+
+  Energy-saving modes are selected with a \#define in @em usbconfig.h, default
+  selection is to not use any energy saving modes.@n @n
+  @verbatim
+#define USB_PWRSAVE_MODE (USB_PWRSAVE_MODE_ONSUSPEND | USB_PWRSAVE_MODE_ENTEREM2)@endverbatim
+
+  There are three flags available, the flags can be or'ed together as shown above.
+
+  <b>\#define USB_PWRSAVE_MODE_ONSUSPEND</b>@n Set USB peripheral in low power
+  mode on suspend.
+
+  <b>\#define USB_PWRSAVE_MODE_ONVBUSOFF</b>@n Set USB peripheral in low power
+  mode when not attached to a host. This mode assumes that the internal voltage
+  regulator is used and that the VREGI pin of the chip is connected to VBUS.
+  This option can not be used with bus-powered devices.
+
+  <b>\#define USB_PWRSAVE_MODE_ENTEREM2</b>@n Enter EM2 when USB peripheral is
+  in low power mode.
+
+  When the USB peripheral is set in low power mode, it must be clocked by a 32kHz
+  clock. Both LFXO and LFRCO can be used, but only LFXO guarantee USB specification
+  compliance. Selection is done with a \#define in @em usbconfig.h.@n @n
+  @verbatim
+#define USB_USBC_32kHz_CLK   USB_USBC_32kHz_CLK_LFXO @endverbatim
+  Two flags are available, <b>USB_USBC_32kHz_CLK_LFXO</b> and
+  <b>USB_USBC_32kHz_CLK_LFRCO</b>. <b>USB_USBC_32kHz_CLK_LFXO</b> is selected
+  by default.
+
+  The USB HID keyboard and Mass Storage device example projects demonstrate
+  different energy-saving modes.
+
+  <b>Example 1:</b>
+  Leave all energy saving to the stack, the device enters EM2 on suspend and
+  when detached from host. @n
