Affected component(s) or functionality

Attaching USB (network) devices

Brief summary

Cannot attach USB WiFI adapter to separate sys-net named disposable qube

To Reproduce
qvm-usb attach sys-net-fedora-37-min sys-usb:1-2
wait for 15-20 seconds
Expected behavior

Attaching should finished successfully

Actual behavior

Got very well known error:

Device attach failed: /usr/lib/qubes/usb-import: line 46: /sys/devices/platform/vhci_hcd/status: No such file or directoryNo unused port found! VM: "sys-net-fedora-37-min" File: "/usr/lib/qubes/usb-import" Version Control: line 81: /sys/devices/platform/vhci_hcd/attach: No such file or directory/etc/qubes-rpc/qubes.USBAttach: line 14: 843 Aborted (core dumped) qrexec-client-vm "$domain" "qubes.USB+$busid" /usr/lib/qubes/usb-import "$statefile" < /dev/null > /dev/null 2> /dev/null

Additional context

My sys-net-fedora-37-min named disposable is running pvgrub2-pvh native 6.0.17-300.fc37.x86_64 kernel.

[user@sys-net-fedora-37-min ~]$ rpm -qa | grep qubes-usb-proxy



Tried quick fix from here, but to no avail:

[user@sys-net-fedora-37-min ~]$ sudo modprobe vhci-hcd 
modprobe: FATAL: Module vhci-hcd not found in directory /lib/modules/6.0.17-300.fc37.x86_64

and only this is found


Device cannot be attached to native kernel running qube.

You need a Github (belonging to Microsoft) account for that. Not everyone agrees with their ToS. I do not.
