Hi.

After recent update my qvm-usb got broken:

Template VM is debian-10

Small update:

Upgraded Debian Template From Debian-10 to Debian-11.
It didn't help unfortunately. Problem persists.

BTW, USB attachment to VM running Fedora-32 Template still works without any problems.

You don't say if you are using 4.0 or 4.1
I don't see this behaviour in either.
Can you test with a vanilla template (either 10 or 11)? Have you made
any modifications to that template?
