 not easily.
 
 i found thsi code in uhidev.c, which is similar to what it needs,
 but it is not enabled:
 
 151 #if 0
 152
 153         qflags =3D usbd_get_quirks(sc->sc_udev)->uq_flags;
 154         if ((qflags & UQ_NO_SET_PROTO) =3D=3D 0 &&
 155             id->bInterfaceSubClass !=3D UISUBCLASS_BOOT)
 156                 (void)usbd_set_protocol(iface, 1);
 157 #endif
 
 so we're never seting this now.
 
 possible, reversing the above to set the protocol to 0 if there
 is a quirk for it would work.
 
 it would be best if someone added real support for this kind of
 keyboard...
