Epson Perfection 1650 suddenly fails

[Anthony Campbell]

This scanner has worked very well for me for many months with xsane.
Following recent upgrade to xsane 0.97 it has stopped working. More
precisely, the first time I try to use it, it seems to work but no
picture appears and the programme hangs and has to be killed. After that
the scanner is no longer detected by xsane: "no device present". If I
unplug it and replug it, it usually comes back.

My tests:

sane-find scanner shows (initially):

"found USB scanner (vendor=0x04b8 [EPSON], product=0x0110 [EPSON Scanner]) at libusb:001:004"

and scanimage -L gives:

"device `epson:libusb:001:004' is a Epson GT-8200 flatbed scanner"

cat /proc/bus/usb/devices shows the scanner is recognized.


What is very odd is that I have a laptop with exactly the same setup as
far as I can see, including the kernel (2.6.10) and this _does_ work
with the scanner.

I've no idea what to check next. Suggestions please? Bug in xsane? (but
vuescan also fails).

After you have rechecked that your cables are properly seated, try
asking Ed Hamrick via his support page. He may be able to reproduce
your issue with VueScan, or may require a VueScan log file.

Yes, I reverted to 0.96 but it made no difference. Cable: yes, I've been
thinking it might be some hardware problem. But it works OK with my
laptop, so I can't think that it's something wrong with the scanner.

I'll try Hamrick as you suggest...

It turns out there was a bug in libusb. Fixed in the latest Debian
release so things are now working again.
