I can't seem to find any examples of how to use the USBD_HIDn_GetReport calback function? I have examples for USBD_HID_GetReportTrigger but nothing for GetReport. Searching the net leads mainly to the define in USBD_User_HID_0.c file.
Are we so-posed to modify USBD_User_HID_0.c to our own design?
Yes, you are supposed.
