scanner problems: I/O error/scanner application hangs

[Erik Nørgaard]

Hi:

I had my scanner, Epson 2480, working half a year ago on FBSD 6.0, now 
it's been a while since I used it, I have upgraded to FBSD 6.1-PREREL as 
well as upgrading applications, and now it doesn't work.

First scanner probe gives an I/O error, second hangs:

charm# date && scanimage -L && date && scanimage -T || date
Fri 24 Feb 2006 23:07:28 CET
device `snapscan:/dev/uscanner0' is a EPSON EPSON Scanner flatbed scanner
Fri 24 Feb 2006 23:07:29 CET
scanimage: open of device snapscan:/dev/uscanner0 failed: Error during 
device I/O
Fri 24 Feb 2006 23:07:29 CET
charm# date && scanimage -L && date && scanimage -T || date
Fri 24 Feb 2006 23:07:33 CET
Killed
Fri 24 Feb 2006 23:09:09 CET

I need to turn off the scanner in order to repeat, it is not enough to 
unplug the usb port.

The scanner is found correctly after applying the patches I submitted 
(pr usb/86094), otherwise it appears as a ugen device.

My system is:
FreeBSD charm 6.1-PRERELEASE FreeBSD 6.1-PRERELEASE #3: Fri Feb 24 
22:25:37 CET 2006     norgaard at charm:/usr/obj/usr/src/sys/CLIENT6  i386

No difference whether uscanner is compiled in kernel or loadable module.

Sane:

sane-backends-1.0.17
sane-frontends-1.0.14_1
xsane-0.991

I believe I had it working with sane-backends 1.0.15 and xsane 0.80

Any ideas?

Thanks, Erik
