I have a
sys-usb qube that is functional, and a Windows 7 HVM with Qubes Windows Tools and updated Xen PV drivers (version 8.2.2), and when I try to attach an USB device to the qube (in this case, a drawing tablet) using
qvm-usb it gives me the following output:
$ qvm-usb -v win7 sys-usb:2-2 Device attach failed:
All possible solutions point to using PCI passthrough to give the qube an USB controller to use, but my computer (ThinkCentre m720q) only has one. What could I do to try to troubleshoot this further?
