I have had the Acer (now Benq) 620UT for years and years. It’s worked on every computer I’ve ever owned. I’ve had it working in Red Hat Linux before and didn’t expect any trouble in Ubuntu. That would have been true if I had not following a tutorial I found online. Since mine was supported by snapscan, in the end I just had to copy the firmware files from the original CD (still have it) and add the file reference to the /etc/sane.d/snapscan.conf file.
firmware /etc/sane.d/prisa/u96v057.bin
Because of the all the things I tried I can’t be sure what else I did had an impact but I believe that this support entry on the brother site for Ubuntu 8.04 may have also contributed:
- Open “/etc/udev/rules.d/40-basic-permissions.rules” file.
Edit “0664” to “0666” in “USB devices” section.
Before the edit———————————
# USB devices (usbfs replacement)
SUBSYSTEM==”usb”, ENV{DEVTYPE}==”usb_device”, MODE=”0664″
SUBSYSTEM==”usb_device”, MODE=”0664″After the edit———————————-
# USB devices (usbfs replacement)
SUBSYSTEM==”usb”, ENV{DEVTYPE}==”usb_device”, MODE=”0666″
SUBSYSTEM==”usb_device”, MODE=”0666″- Restart the OS.
