Comment # 20 on bug 1174406 from Johannes Kehrer

Sorry,
the output is like this:
"
~> VBoxManage list usbhost
Host USB Devices:

<none>
"

Then I tried your second command and attached to the post before (sorry for
this).

VBoxSVC.log is from the Directory "~/.config/VirtualBox/".
there are another 10 Backup (VBoxSVC.log.x).

Thanks,
Johannes
