Hi.

After recent update my qvm-usb got broken:

[user@dom0 ~]$ qvm-usb
BACKEND:DEVID DESCRIPTION USED BY
sys-usb:2-1 Generic_EMV_Smartcard_Reader
sys-usb:2-10 8087_0aaa

[user@dom0 ~]$ qvm-usb a myvm sys-usb:2-3

[user@dom0 ~]$ rpm -q -a | grep -i usb | grep -i qub
qubes-usb-proxy-dom0-1.1.0-1.fc25.noarch

Template VM is debian-10

user@debian-10:~$ dpkg -l | grep -i qub | grep -i usb
ii qubes-usb-proxy 1.1.0+deb10u1
amd64 USBIP wrapper to run it over Qubes RPC connection

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?
