Error 94, I/O Error

Hello,

I have a Framework13 laptop running a fully updated 4.2.4. Failure occurs when attempting to attach my bluetooth module from sys-usb to disp-sys-audio:

[Doug@dom0 ~]$ qvm-usb attach --verbose disp-sys-audio sys-usb:4-10
Device attach failed: /usr/lib/qubes/usb-import: 94: echo: echo: I/O error.

The bluetooth module will connect to other qubes, just not disp-sys-audio.

disp-sys-audio is running debian-12-minimal.
sys-usb is debian-12.

Any help or thoughts are appreciated.

Thanks.

After doing some more research, I found the answer in a post in the qubes-public chat room: install USBGuard. It works.
