Recently I became a fan of VirtualBox, the virtualization platform from Sun Microsystems. It’s robust, it has an extremely small memory foot-print comparing it to other similar virtual managers and it has some great features. You can find more about it on its homepage.
Yesterday I have updated VirtualBox from 2.2.4 to 3.1. Unfortunately, the USB support failed to work despite the fact that I did install VirtualBox Guest Additions to my guest machines. The solution to fix it is pretty simple:
add your user to the
useradd -G vboxusers yourusername
check the group id (the number that appears in the output):
grep vboxusers /etc/group
add the following line in
none /proc/bus/usb usbfs devgid=xxx,devmode=664 0 0
where xxx stands for the group id
remount all the devices in
sudo mount -a
or if this doesn’t work simply reboot your machine.
Afterwards all should work like a charm.
