Virtualbox usb passthrough not working


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 ?

This was already discussed in the forums. And there is also a bugreport

Thank you for informing me !
