This is an attempt to add support for the E3 chipset based scanners such as the Genius Vivid Pro USB scanner. In theory it should support the following scanners as they use the same chipset. Can you please let me know if your scanner is supported.
* Genius Vivid Pro USB
* Primax Colorado USB 19200
* Visioneer OneTouch 7600
* Visioneer OneTouch 6100
* IBM IdeaScan 2000 USB
* LG Electronics Scanworks 600U
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.
