Some bug with 4.3, cannot use USB widget. It assume the qube handling USB is named “sys-usb”, on my system that not the case and using multiple usb qubes.

### Qubes OS release 4.3 ### Brief summary The widget expects the USB vm to b…e named "sys-usb", but when installing on system with only USB internet and clicking option to merge sys-net and sys-usb, the USBVm is named "sys-net". The issue can be worked around by replacing a "sys-usb" string literal in a python file in /usr/lib with "sys-net". The widget freezes, doesn't appear. ### Steps to reproduce Install Qubes OS with merged sys-net and sys-usb. Try to use devices widget. Observe it not working. ### Expected behavior Widget works no matter how the USB vm is named (or the installer should call the NETvm sys-usb) ### Actual behavior The widget freezes, doesn't appear.
