USB

To get USB support, need jiaohuan/'>the PUEL (non-free) version. Via GUI, there is an option enable USB. Furthermore, your user must be able access /proc/bus/usb/* Since Gutsy, /proc/bus/usb is not mounted by default. Version 2.0.6 removes the need for the following lines to be added, but /proc/bus/usb must still be mounted. Previously, in Intrepid, you needed to add the following lines to /etc/init.d/mountdevsubfs.sh right after domount devpts "" /dev/pts devpts -onoexec,nosuid,gid=$TTYGRP,mode=$TTYMODE but before the ending } for the dostart shell function. For Gutsy and Hardy you just need to edit /etc/init.d/mountdevsubfs.sh and uncomment the following lines:

        #
        # Magic to make /proc/bus/usb work in virtualbox version < 2.0.6
        #
        mkdir -p /dev/bus/usb/.usbfs
        domount usbfs "" /dev/bus/usb/.usbfs usbfs -obusmode=0700,devmode=0600,listmode=0644
        ln -s .usbfs/devices /dev/bus/usb/devices
        mount --rbind /dev/bus/usb /proc/bus/usb

Then run the script that you just edited:

sudo /etc/init.d/mountdevsubfs.sh start

In order to give users in the vboxusers group write permissions to the devices in /proc/bus/usb, you'll need to edit some rules in /etc/udev/rules.d. Under Gutsy, edit /etc/udev/rules.d/40-permissions.rules to say the following:

# USB devices (usbfs replacement)
SUBSYSTEM=="usb_device",                MODE="0664", GROUP="vboxusers"

Under Hardy and Intrepid, edit /etc/udev/rules.d/40-basic-permissions.rules to say the following:

# USB devices (usbfs replacement)
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0664", GROUP="vboxusers"
SUBSYSTEM=="usb_device",                MODE="0664", GROUP="vboxusers"

Then, restart the udev service:

sudo /etc/init.d/udev restart

Now, if you haven't done it already, make sure your user is part of the group vboxusers using the following command:

sudo usermod -G vboxusers -a `whoami`
