Without knowing what global items are it might be difficult to make sense from some HID descriptors. Under Linux, libusb simply ignores all the descriptor-related stuff and works as it is told to, but under Windows, well, libusb-win32 is a monster I never actually convinced to work as I want. We are using a HID test APP and comparing our values to a known good GAMEPAD (Steel Series BLE gamepad) Everything is working EXCEPT one big problem. it is nesessary, but why?
