How to Enable USB Devices for VirtualBox Guests in Fedora 11

| Comments

By default, guest hosts running in VirtualBox on Fedora 11 cannot mount or see usb devices plugged into your machine. A few tweaks are necessary for USB support to work.

  1. Edit your /etc/rc.sysinit file, change line no 26 from
mount -n -t usbfs /proc/bus/usb /proc/bus/usb


mount -t usbfs -o remount,devgid=$(awk -F: '/^vboxusers:/{print $3}' /etc/gr    oup),devmode=664 /proc/bus/usb /proc/bus/usb

So, your /etc/rc.sysinit should change from:

 23 if [ ! -d /proc/bus/usb ]; then
 24         modprobe usbcore >/dev/null 2>&1 && mount -n -t usbfs /proc/bus/usb     /proc/bus/usb
 25 else
 26        mount -n -t usbfs /proc/bus/usb /proc/bus/usb
 27 fi


 24         modprobe usbcore >/dev/null 2>&1 && mount -n -t usbfs /proc/bus/usb     /proc/bus/usb
 25 else
 26 #       mount -n -t usbfs /proc/bus/usb /proc/bus/usb
 27 mount -t usbfs -o remount,devgid=$(awk -F: '/^vboxusers:/{print $3}' /etc/gr    oup),devmode=664 /proc/bus/usb /proc/bus/usb
 28 fi
  1. Next, edit your /etc/udev/rules.d/10-vboxdrv.rules. Change line number 1 from
KERNEL=="vboxdrv", NAME="vboxdrv", OWNER="root", GROUP="root", MODE="0600"


KERNEL=="vboxdrv", NAME="vboxdrv", OWNER="root", GROUP="root", MODE="0660"
  1. Reboot your machine. You should now be able to mount you usb devices.

The following screenshot shows some of the USB devices can allow my guest machine to view. [caption id=”attachment_164” align=”aligncenter” width=”300” caption=”The USB devices available for VirtualBox Guests”]The USB devices

Devices like my USB Flash Drive are still blurred out. In order to get them to work, I need to install the VirtualBox Guest Additions first.
