If you could work on it yourself that would be great FWIW, I tried playing with the new HID_REPORT_DESCRIPTOR but if this allows to read the current report descriptor, this doesn't allow to amend it, making things a little bit too complex to implement properly. So it would be simple enough to use the same old bits checking and changing so you get the BPF quickly out. Cheers, Benjamin > > I can test it anytime. > > Cheers, > Ruzal >
