Function Documentation

void HIDMSDDriver_ConfigurationChangedHandler

(

uint8_t

cfgnum

)

Invoked whenever the configuration value of a device is changed by the host

Parameters:

cfgnum

Configuration number.

void HIDMSDDriver_Initialize	(	const USBDDriverDescriptors *	pDescriptors,
		MSDLun *	pLuns,
		uint8_t	numLuns
	)

Initializes the USB device HIDMSD device driver.

void HIDMSDDriver_RemoteWakeUp

(

void

)

Starts a remote wake-up sequence if the host has explicitly enabled it by sending the appropriate SET_FEATURE request.

void HIDMSDDriver_RequestHandler

(

const USBGenericRequest *

request

)

Handles HIDMSD-specific USB requests sent by the host, and forwards standard ones to the USB device driver.

Parameters:

request

Pointer to a USBGenericRequest instance.
