Called by USBDevice layer on each new USB frame.

Callbacks are enabled and disabled by calling sof_enable and sof_disable.

Implements USBDevice.

void complete_request	(	RequestResult	result,
		uint8_t *	data = `NULL`,
		uint32_t	size = `0`
	)

protectedinherited

Called to complete the setup stage of a callback request.

Possible options that can be passed as a result are:

Receive - Start the data OUT phase of this control transfer
Send - Start the data IN phase of this control transfer
Success - Operation was a success so start the status phase
Failure - Operation failed or is unsupported so send a stall
PassThrough - Pass on the request for standard processing

Parameters

result	The result of the setup phase.
data	Buffer to send or receive if the result is Send or Receive
size	Size to transfer if the result is Send or Receive

void complete_request_xfer_done ( bool success )

protectedinherited

Called to complete the data stage of a callback request.

Parameters

success true if the operation was successful, false otherwise

void complete_set_configuration ( bool success )

protectedinherited

Called to complete a set configuration command.

Parameters

success true if the configuration was set, false otherwise

void complete_set_interface ( bool success )

protectedinherited

Called to complete a set interface command.

Parameters

success true if the interface was set, false otherwise

bool configured ( )

void connect ( )

inherited

Connect a device This method can also be used to resume USB operation when USB power is detected after it was suspended via USBDevice::deinit.

void deinit ( )

inherited

Power down this instance.

Disable interrupts and stop sending events. This method can be used for temporary power-saving; This call can allow USB to be temporarily disabled to permit power saving. However, it is up to the user to make sure all the transfers have concluded (for example when USB power is lost). USBDevice::connect can be used to resume USB operation.

void disconnect ( )

inherited
