Several things have happened since it stopped working,Failed to scan unable to connect to scanner
1) I moved my equipment to another room
2) I upgraded Linux Mint Kernal several times.
I have an HP PSC 2200 all in one printer connected via USB, the printer works without any problems, I can print.
scan image produces the following
sane-find-scanner produces the following$ scanimage -L
device `hpaio:/usb/PSC_2200_Series?serial=MY35CF70CV0G' is a Hewlett-Packard PSC_2200_Series all-in-one
Simple Scan shows the correct scanner.$ 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.

# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.
# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.
# You may want to run this program as root to find all devices. Once you
# found the scanner devices, be sure to adjust access permissions as
# necessary
I have checked that user and printer are in the same group so permissions should not be a problem, indeed if it were a permissions issue then I'm guessing that sane-find-scanner would fail
This has previously worked perfectly.
I have re-installed simple scan and the CUPS printer several times to no avail, any help appreciated
