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;
+	}
