The USB pass-through used to work flawlessly until quite recently. Don’t know when it stopped but now VBox is reporting (in the Host GUI) that there are “<no devices available>” .
I have spent days going through the basic USB troubleshooting (Extension Pack, vboxuser, enable/disable file, 60.etc) with no luck.
I have even performed a fresh installed of openSUSE 15.5 on a test PC and then installed VBox from: https://download.opensuse.org/repositories/openSUSE:/Leap:/15.5/standard/.
The only suspect I can find (but don’t know how to follow) is:
mprowe@Gzunder:~> VBoxManage list usbhost
Host USB Devices:
<none>
But:

Any pointer will be most welcome. VBox AND USB are very useful, and I’m lost without them!
