Edit "/sys/dev/usb/uhid.c":
Where you find:
sc->sc_isize = hid_report_size(desc, size, hid_input, &sc->sc_iid);
sc->sc_osize = hid_report_size(desc, size, hid_output, &sc->sc_oid);
sc->sc_fsize = hid_report_size(desc, size, hid_feature, &sc->sc_fid);
Add here:
if(sc->sc_isize > UGETW(ed->wMaxPacketSize))
sc->sc_isize = UGETW(ed->wMaxPacketSize);
