[sane-devel] Using a Visioneer Strobe XP 100 or Syscan Travelscan 464 with SANE (long)

I would like to get either the Syscan Travelscan 464 or the Visioneer 
Strobe XP 100  working with  SANE.  Both of these USB scanners seem nearly 
identical and use the LM9832 chip inside. Neither currently has a Linux 
SANE driver (or do they?  anyone have more info?)
When I plug either of these scanners into the USB port on my RedHat 8.0 
system, I can see them using the "lsusb" command. By reading various 
sources, I was able to figure out for the Travelscan 464, specifically, 
that I needed to add the "options scanner 0xa82 0x4600" to /etc/modules.conf.

After doing that, when I do a "rmmod scanner" and "modprobe scanner" and 
then "lsmod" it says the scanner module is loaded.

OK, so now I am getting this message when I do a "sane-find-scanner":

# No SCSI scanners found. If you expected something different, make sure 
that ...[yada yada]

found USB scanner (vendor=0x0a82 [SYSCAN], product=0x4600 [TravelScan 460]) 
at libusb:001:005

# A USB device was detected.

This program can't be sure if it's really # a scanner. If it is your 
scanner, it may or may not be supported by # SANE. Try scanimage -L and 
read the backend's manpage. ...[yada yada]
So I need middleware, so I downloaded the latest sane-backend and the 
plustek driver code from the Web page (I started there, because it already 
supports several LM9832 scanners).  I did the recommended changes to the 
source code (plustek-devs.c) in order that it would recognize the 
Travelscan.  Then I did the make, make install, etc.  Everything seemed to 
work OK.

But now, when I do a "scanimage -L" now, I just get this message:

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).

The "sane-find-scanner" command still works as described earlier.
Someone suggested that I try a "Scanimage -d plustek:usb/dev/usb/scanner0". 
So, I tried that, then I get this message:

scanimage: open of device plustek:usb/dev/usb/scanner0 failed: Error during 
device I/O

Any suggestions on what I should try next?  Perhaps a different scanner driver?

Thanks, - Ted
