[libvirt-users] ergodox keyboard not working on USB hostdev passthrough
I'm using a bit of a different keyboard, the infinity ergodox [ https://input.club/devices/infinity-ergodox/]. It functions just fine as a keyboard on my host computer, but when I try to bind it to the guest, nothing seems to happen. lsusb gives its ID: Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub *Bus 005 Device 003: ID 1c11:b04d* Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 258a:0001 Bus 001 Device 002: ID 093a:2521 Pixart Imaging, Inc.

I bought a cheap keyboard to test out, and it works just fine. My pet keyboard, however, doesn't work on the guest. Nothing seems to register. Any ideas here what I could do? Drivers? ROM's? I've tried both SeaBIOS and OVMF with no difference in outcome, and while this appears to be a hardware problem, I don't know where to begin. Thanks, Paul

Since the guest can see it ^^ I don't think this is a problem in the host system. Does it require special module/driver? Is it supported by the guest OS? When it is not passed-through to your guest, run lsusb -t on the host and see what's the Driver= for the device. The try the same thing in the guest and if it's missing you got it. If not, then you can check settings for X etc.
The mouse works just fine. I bought a cheap keyboard to test out, and it works just fine. My pet keyboard, however, doesn't work on the guest. Nothing seems to register.
