|
|
* This file contains the USB endpoint 0 management routines corresponding to
|

|
|
* 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.
