Everything worked absolutely flawlessly under 1.0.18.
After the upgrade, which according to the ChangeLog added this
device (usb 0x4b8 0x818) to backend/epson_usb.c (which I thought
would make everything work better), I can't get scanimage (or any
other program for that matter) to see the device (even though
sane-find-scanner does).
If I downgrade back to 1.0.18, then everything works again.
I don't know what you need to diagnose this, but let me start
with:
# 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.
# Also you need support for SCSI Generic (sg) in your operating system.
# If using Linux, try "modprobe sg".
found USB scanner (vendor=0x04b8 [EPSON], product=0x0818 [USB MFP]) at
libusb:004:012
# 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.
# 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).

I did notice under 1.0.18, I got these messages in /var/log/messages:
usb 4-2: usbfs: interface 1 claimed by usblp while 'scanimage' sets config #1
usb 4-2: usbfs: interface 1 claimed by usblp while 'scanimage' sets config #1
But under 1.0.19, I get this instead:
usb 4-2: usbfs: interface 1 claimed by usblp while 'scanimage' sets config #1
usb 4-2: usbfs: interface 0 claimed by usbfs while 'scanimage' sets config #1
I would appreciate any help you can give me with this.
Thank you in advance.
