Hi Elliott-Brennan I have just gone through this with a Acer 640u scanner so what you have done so far is correct, the only other thingI did different was to delete all the scanner entries under /dev
This then allows libusb to handle the devices. Note this was done using: Linux 2.6.x libusb usbfs mount the usbfs mount -t usbfs -o defaults,devmode=0666 /proc/bus/usb none none or in fstab add none /proc/bus/usb usbfs defaults,devmode=0666 0 0 Adjust permission as you see fit, though root should work. I created a group scanner and adjusted the owners, groups and perms, see man mount for details on options for device mount options.
