port	(not used)
lowspeed	true if device is low speed

Returns: 0 for success

Reimplemented from USBDeviceConfig.

Definition at line 333 of file masstorage.cpp.

◆ ConfigureDevice()

uint8_t BulkOnly::ConfigureDevice	(	uint8_t	parent,
		uint8_t	port,
		bool	lowspeed
	)

virtual

USB_ERROR_CONFIG_REQUIRES_ADDITIONAL_RESET == success We need to standardize either the rcode, or change the API to return values so a signal that additional actions are required can be produced. Some of these codes do exist already.

TECHNICAL: We could do most of this code elsewhere, with the exception of checking the class instance. Doing so would save some program memory when using multiple drivers.

Parameters

parent	USB address of parent
port	address of port on parent
lowspeed	true if device is low speed

Returns

Reimplemented from USBDeviceConfig.

Definition at line 258 of file masstorage.cpp.

uint8_t BulkOnly::Poll ( )

virtual

For driver use only.

Returns

Reimplemented from USBDeviceConfig.
