Setting up USB on Ubuntu 7.04
Contributed by Ibrahim Ben Faruhn, 2007/06/14
After I had a taken a look into the insides of Ubuntu 7.04, I managed to get VirtualBox's USB-Support working there in such a way that the user only needs to be a member of a group called usbusers. This howto describes how I did it.
Basically, you just have to tell Ubuntu that a group called usbusers should have read and write access to all usb devices.
1. Create a group called usbusers
2. Add yourself to this group
3. Edit the file /etc/udev/rules.d/40-permissions.rules (for this, you must have administrative privileges)
3.1 Search for the following lines
# USB devices (usbfs replacement)
SUBSYSTEM=="usb_device", MODE="0664"
3.2 Change them to the following
# USB devices (usbfs replacement)
SUBSYSTEM=="usb_device", GROUP="usbusers", MODE="0664"
4. Restart your PC
5. You should now have write access to all usb devices.
