[sane-devel] Epson 1650 doesn't work with Fedora Core 2

[Glen R. Salo]

I have been unable to get my Epson 1650 to work with Fedora Core 2.  I have 
found many related discussions, but nothing seems to work, even as root.  The 
scanner seems to be found with sane-find-scanner, but not with scanimage.

The output of sane-find-scanner (as root):
  # No SCSI scanners found. If you expected something different, make sure 
that
  # you have loaded a SCSI driver for your SCSI adapter.
 
found USB scanner (vendor=0x04b8 [EPSON], product=0x0110 [EPSON Scanner]) at 
libusb:003:002
  # Your USB scanner was (probably) detected. It may or may not be supported 
by
  # SANE. Try scanimage -L and read the backend's manpage.
 
  # Scanners connected to the parallel port or other proprietary ports can't 
be
  # detected by this program.

The output of scanimage -L (as root):
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).

I have checked the file permissions, epson.conf, and libsane.usermap as shown 
below.  Any suggestions on what I should try next?

Thanks,

Glen

The file permissions in /proc/bus/usb/003 are:
-rw-rw-rw-  1 root root 43 Sep  6 20:04 001
-rw-rw-rw-  1 root root 50 Sep  6 20:04 002
-rw-rw-rw-  1 root root 52 Sep  6 20:04 003

The current version of /etc/sane.d/epson.conf:
# epson.conf
#
# here are some examples for how to configure the EPSON backend
#
# SCSI scanner:
scsi EPSON
#
# Parallel port scanner:
#pio 0x278
#pio 0x378
#pio 0x3BC
#
# USB scanner - only enable this if you have an EPSON scanner. It could
#               otherwise block your non-EPSON scanner from being
#               recognized.
#               Depending on your distribution, you may need either the
#               first or the second entry.
#usb /dev/usb/scanner0
#usb /dev/usb/scanner0
 
# Try USB printers -- this line is required (bug #122328)
usb 0x4b8 0x0110


The entry for the scanner in /etc/hotplug/usb/libsane.usermap is:
# Epson Corp.|Perfection 1650 / 1650 Photo
