Ubuntu 8.04: USB Devices in Guest O/S with Virtual Box

Once Virtual box is installed and working, you might find USB devices unrecognized or giving Error about no permission in usbfs ...

The Solution for this issue:

Check if the group id for vboxusers: (should have been created as part of installing Vbox.)

$ more /etc/group | grep vboxusers

result: vboxusers:x:124:username (where username is your username)

Edit fstab:

$ sudo nano /etc/fstab

Add the following lines to the fstap file.

# virtualbox group id = 124 (see previous)
none /proc/bus/usb usbfs devgid=124,devmode=664 0 0

 
mount all fstab devices after changes:

$ sudo mount -a
