Hello,
I have opensuse tumbelweed and I have virtualbox installed through zypper.
I cannot pass the usb to the guest vms, as I can see them but they are unavalable / grey out.
I checked that I am at proper vboxusers group, I tried many files on /etc/udev/rules.d/ (I also copy one from ubuntu which works fine!), without any result.
Lastly I check that the file enable exists on .config/virtualbox/
Any idea what else I can do to have USB Passthrough to vm Guests ?
