This bug is mentioned in openSUSE-2024-134 - Recommended update for virtualbox; - Setting 0660 as permissions of /dev/vboxusb directory itself was preventing access to this directory by any non-root user, even if member of vboxusers. This results in VBox UI failing to enable USB passthrough. Fix issue by removing all the workarounds for /dev/vboxusb/* as they should no longer be required. Fixes boo#1222408.
