I vaguely recall this wasn't the case at all for the older generations 
I've had my hands on, and it wasn't just the matter of 
HID_QUIRK_NO_INIT_REPORTS quirk.

But anyway ... that wasn't reported as a regression for quite some time, 
so let's defer to what Ping and Jason have to say regarding 
protocol/driver compatibility.

I'll be pushing the RMI fix to Linus soon.

Thanks,
