Hi everyone,
I have an Epson Perfection 2480 Photo scanner and it was working with
sane. After a while I need this scanner again but it is not working anymore.
I got some "Pipe error" messages using sane-find-scanner. Is it broken?
# sane-find-scanner
could not fetch string descriptor: Pipe error
could not fetch string descriptor: Operation timed out
could not fetch string descriptor: Operation timed out
found USB scanner (vendor=0x04b8, product=0x0121) at libusb:003:007

# Your USB scanner was (probably) detected. It may or may not be
supported by
# SANE. Try scanimage -L and read the backend's manpage.
# scanimage -L
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
