[sane-devel] Fwd: xane timeout if do scan after preview

[Steven King]

Hi

 I've been experimenting some more. The problem is not when I scan after I 
preview, it is if I scan after changing the scan area. My earlier experiments 
had a small image on the flatbed, and so the scan area was being amended 
automatically. I can scan as much as I want, but only if I avoid changing the 
scan area. Not great.. Any clues?

(If this is a known problem in xsane 0.84, then I will do the upgrade, I just 
don't want to do it only to find it makes no difference.)

Thanks

Steve

Hello

I have previously had xsane etc working on my scanner, but had an accident
 and have to do some reinstalling. (No backups - accident happened while
 trying to get a cd writer working .... ironic really...) Now I cannot get my
 scanner working properly again.

It seems like a very precise problem, so I hope someone can easily pinpoint
it:

I do a scan preview, and this works well. Then I do an actual scan, and this
fails. By "fails", I mean: the scanner jolts a bit and after a while I get
"usb_control/bulk_msg: timeout" in my console output. I have to restart linux
to get the scanner available again.

So I did some experiments:

(a) I can do as many scan previews, one after the other, as I like - they all
work.

(b) I can do as many actual scans as I like, one after the other - they all
work.

(c) I can do an actual scan followed by a preview - they both work.

So it *only* when I do a preview followed by an actual.

I have said this is a new problem since I reinstalled things. That is not
quite true. It now happens 100% of the time; before it was a very occasional
problem.

When I do sane-find-scanner, it sees my scanner, which is at /dev/usbscanner.
(Oddly, if I do that as root, it finds my scanner twice: once as
/dev/usbscanner and once as /dev/usb/scanner0.)

Installation info:

The scanner is HP 2100C Scanjet
My kernel is 2.4.10-4GB
sane backends 1.0.8-5
sane-frontends 1.0.8-4
xsane 0.84-8 (after this version there are a lot of dependencies that I do
 not have, and some are quite large to download, so I do not want to use them
 if I can avoid it)

Any clues, please?

Thanks

Steve
