MxPS= 8 Ivl=10ms Interestingly, the usbmon trace shows that the interrupt endpoint for interface 1 isn't being used by usbhid. I don't know why, but it shouldn't make much difference for your purposes since that interface appears to be associated with the gaming interface. But maybe I'm wrong and it is important somehow... The other noticeable thing is that the keyboard didn't accept the Set-Idle request for interface 1. You said before that the keyboard worked okay when driven by a guest Windows OS, right? Can you collect an equivalent usbmon trace for that? Comparing the two traces may be instructive.
