Troubleshooting USB trezor not seen by Qubes?

I have used this Trezor on Qubes before but now when I plug it in, it doesn’t pop up and doesn’t appear in the USB taskbar/list thing so I cannot assign it to any Qubes. Any ideas why? I tried rebooting and still no luck. Other USB devices seem to work. The Trezor powers on and shows its logo when it is plugged in. Still on Qubes 4.0.
