Can you elaborate why you remove the special handling from USBHID but add it to UHID? They both operate logically on the same level, so shouldn't we simply adjust uhid to include the report-id in buf[0]? Also, you override buf[0] in UHID, so I wonder what UHID currently returns there? IOW, can you elaborate a bit what the current behavior of each of the involved modules is, and what behavior you would expect? This would allow to better understand what you are trying to achieve. The more context you can give, the easier it is to understand what happens there. Thanks! David
