Scanner that worked with Ubuntu 10.4 cannot be found by 13.4
- by stevecoh1
My computer previously ran Ubuntu 10.4. After upgrading to 13.4, my Epson scanner no longer can be found by the system. Following documentation, I find the following:
$ sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.
could not open USB device 0x046d/0x082b at 001:007: Access denied (insufficient permissions)
...
# No USB scanners found. If you expected something different, make sure that
# you have loaded a kernel driver for your USB host controller and have setup
# the USB system correctly. See man sane-usb for details.
...
If I instead run sudo sane-find-scanner, I get
$ sudo sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.

# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.
So what do I do? scanimage -L does nothing for me and I don't know what the "backend's manpage" might be. It's seems likely that this is a permissions issue since the scanner can be found as root, but I don't know how to solve it. Can someone help?
