Virtualbox and USB passthrough

since the last update of Virtualbox the USB passthrough doesn’t work anymore.

The ~/.config/VirtualBox/VBoxSVC.log sais:

00:00:01.695707 nspr-5   WARNING [COM]: aRC=NS_ERROR_FAILURE (0x80004005) aIID={16ced992-5fdc-4aba-aff5-6a39bbd7c38b} aComponent={HostWrap} aText={VirtualBox is not currently allowed to access USB devices.  You can change this by adding your user to the 'vboxusers' group.  Please see the user manual for a more detailed explanation}, preserve=true  aResultDetail=0

However, I am member of the group ‘vboxusers’:

Johannes@JohannesOffice:~> id
uid=1000(johannes) gid=100(users) Gruppen=100(users),457(vboxusers),486(kvm)

Can anybody tell me which owner:group on which files I have to correct?


Is the Virtualbox installed on your machine installed from the openSUSE repositories or from the oracle website?

Although there are no indications the kernel or kernel modules might be related to your problem, if you have multiple kernels you should try booting to an earlier kernel just to see if it works anyway. If it works, then your last upgrade likely included a new kernel and kernel modules might be affected (nothing you can do if that’s the case unless you want to build your own).

If your pass-through was working before the last TW upgrade, then you might need to submit a bug to
Be sure to include
Current TW version
Current kernel, both HostOS and Guest
Current Virtualbox version.

exact error thrown.


Perhaps you need to install an updated extension pack?

Perhaps if the question is using the USB virtualization driver.

But if the @OP is really trying to do a pass-through, I doubt updating the extension pack would make a difference.
