VirtualBox USB Voodoo for Gutsy

Filed under: LiveCD,Ubuntu — burner @ 11:25 pm  

By default, USB support doesn’t work in Gutsy even if you download the latest and greatest here.

To remedy this:

  1. alt+f2, gksudo gedit /etc/init.d/mountdevsubfs.sh
  2. Look for the part about magic and make it say this:
  3. #
    # Magic to make /proc/bus/usb work
    mkdir -p /dev/bus/usb/.usbfs
    domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
    ln -s .usbfs/devices /dev/bus/usb/devices
    mount --rbind /dev/bus/usb /proc/bus/usb

  4. Save the file and run the script via alt+f2, gksudo /etc/init.d/mountdevsubfs.sh
  5. Restart VirtualBox and bask in the glory of a USB icon under Settings for your virtual machine



upgraded to the latest and I don’t see a magic section in that file. Can you just add it? Thanks

Thank you so much.

I have been looking for a real fix for this and there are all sorts of “work arounds” but this is the only one that worked! I really appreciate it.

[…] ich ein bisschen gesucht habe (nicht gegooglelt, sondern geyahoot) fand ich dann recht schnell die Lösung auf dem Blog von buranen.info. Da unter Gutsy jene Unterstützung per default deaktiviert ist, […]


Vielen vielen Dank, das funktioniert hervorragend 🙂

bei mir klappts anscheinend nicht:
usb auswahl wird weiterhin nicht angezeigt

bekomme nach:
gksudo /etc/init.d/mountdevsubfs.sh

folgende meldung
ln: Erzeugen der symbolischen Verknüpfung „/dev/bus/usb/devices“ zu „.usbfs/devices“: File exists

ist das normal..
was ist zu tun?

danke für eure tipps

I got the same message as flo. And the USB support is still not availible. Has anybody found a solution for this problem?

Das gleiche Problem wie flo habe ich auch. Gibt es eine Lösung?

Das Problem hat sich erledigt: USB wird nun angezeigt.

Pauschi @ December 17, 2007 4:20 pm


hi all,

I had the same problem.

Additional to the procedure described above I had to add the following line to the /etc/fstab:

none /proc/bus/usb usbfs devgid=XXXX,devmode=664 0 0

XXXX ist the group id of vbxusers group.
