Functions
void	usb_process_request (void)
	This function reads the SETUP request sent to the default control endpoint and calls the appropriate function.
Variables
U8	usb_configuration_nb
	Public : (U8) usb_configuration_nb Store the number of the USB configuration used by the USB device when its value is different from zero, it means the device mode is enumerated Used with USB_DEVICE_FEATURE == ENABLED only /.
U8	otg_device_nb_hnp_retry
	Public : (U8) otg_device_nb_hnp_retry; Counts the number of times a HNP fails, before aborting the operations.

USB device enumeration requests header file.

This file contains the USB endpoint 0 management routines corresponding to the standard enumeration process (refer to chapter 9 of the USB specification. This file calls routines of the usb_specific_request.c file for non-standard request management. The enumeration parameters (descriptor tables) are contained in the usb_descriptors.c file.
