You could maybe try this. Lookup the following code in ukbd.c. Add the lines
marked with +
if (sc->sc_kbd_id != 0) {
/* check and remove HID ID byte */
usbd_copy_out(pc, 0, &id, 1);
if (id != sc->sc_kbd_id) {
DPRINTF("wrong HID ID\n");
goto tr_setup;
}
offset = 1;
len--;
} else {
offset = 0;
}
+ if (len == 12) {
+ offset += 2;
+ len -= 2;
+ }
+ if (len == 11) {
+ offset += 1;
+ len -= 1;
+ }
