Yubikey without sys-USB

[baflya]

Hello,

i am trying to use a Yubikey in some AppVM but it does not show up in the device manager, when not using a USB-Qube. With the USB Qube it works, but for some reason (USB Audi device, needs to be in dom0, and only having 2 USB controllers) i cannot use a setup with sys-usb.

Also, you can create sys-audio and use it as sys-usb as well:
