+/* LAB10_USBHID_pnp
+ *
+ * This is a simple Generic HID demo, which is more or less
+ * compatible with the USB HID PnP demo example from the
+ * Microchip Applications Library, so that the PC application 
+ * from that package can be used with our firmware as well
+ * (after two small modification).
+ *
+ * The differences:
+ * - We use 12 bit ADC resolution (instead of 10 bit)
+ * - We use Vid=0x0483, Pid=0x5750 which are the official
+ *   STM32 Custom Human Interface Device identifiers from
+ *   ST Microelectronics.
