no USB device available

[fbusse]

I have installed VirtualBox from the Oracle sources, including Guest Additions and Extension Pack (all v4.2.12 r84980), and I'm member of vboxusers, host is Lubuntu 12.04 (precise), guest is a fresh XP Home/SP2.

USB-devices connected to the host (and correctly recognized, and usable) are not recognized by VirtualBox: According to the guests' devices menu no USB device is connected (German version: "Kein USB-Gerät angeschlossen").

Any idea where I should have a closer look at?

Did you log off or reboot the host after you added your name to the vboxusers group?

Sorry, I forgot to mention that: Yes, I finished the install (including adding myself to vboxusers) some days ago, and even shut down and freshly started the system several times.

Where do you get your version of VirtualBox?

Where do you get your version of VirtualBox?

from the Oracle source (as mentioned in the original post), i.e.

Code: Select all

http://download.virtualbox.org/virtualbox/debian

still unsolved, but at least, after a hint from a friend, it seems that I'm stepping closer...

USB devices are smoothly available when running VB as root: Obviously, as a normal user, I'm lacking necessary access rights.

After manually (temporarily) adding to the fuse group, USB devices show up in "VBoxManage list usbhost", but still as "unavailable". (In "sudo VBoxManage list usbhost", the same device is marked "busy".)

Inserting a filter for a USB device has no visble effect.

Any ideas, anybody out there?

And in addition the being a member of vboxusers group, you will need the udev rule /etc/udev/rules.d/60-vboxdrv.rules that makes usb devices available to vboxusers. This set of rules should have been installed by the VirtualBox installer.
