Sys-usb freezes screen when started

I run Qubes OS 4.2.4 and 9950x CPU, I had to disable creation of sys-usb during initial setup due to a bug. Help much appreciated.

I created sys-usb by following @Sven recommendations from 2022 in this post Cannot create sys-usb via salt - #28 by Sven with following commands, which might well be outdated but I couldn’t find more relevant commands, please let me know if there is!

qvm-create --template fedora-41-xfce --label red sys-usb

qvm-prefs sys-usb virt_mode hvm
qvm-prefs sys-usb autostart true
qvm-prefs sys-usb netvm ''

qvm-pci attach sys-usb --persistent dom0:*
qvm-pci attach sys-usb --persistent dom0:*
qvm-pci attach sys-usb --persistent dom0:*
qvm-pci attach sys-usb --persistent dom0:*

qvm-start sys-usb

Which would freeze my screen and apparently any input as “sys-usb is starting” message appears. I am not aware how to extract logs in that case so please let me know if there is a way.

It’s probably related to one of those devices. Try to attach them only one at a time to find which one is problematic.
