[sane-devel] Umax Astra 2200, USB, SuSE 9.0. Sometimes (!) scanning/preview fails.

Fri Oct 31 14:49:15 GMT 2003

Hi,

I use Umax 2200 (SU) with USB under SuSE 9.0 (Kernel
2.4.21-99). sane backend version 1.0.12. xscanimage (sane-frontends)
1.0.10.

I have problem with scanning which some others in this list had too
[1], but the answers do not solve my problems. So I am verbose.

At first good news: The scanner is recognized by the system :-)

~> sane-find-scanner

So far everything is fine!

BUT sometimes (!) I get PROBLEMS while scanning. :-(
I use ~> xscanimage (e.g.)

Sometimes while getting the preview the scanner stops and xscanimage
freezes. But sometimes I get the preview with the same settings
without problems. I cannot see any rule behind it.

Aquiring the preview:

1min later: aquiring the preview with exact the same settings, but the
scanning fails

Scanner stops.

BTW: [ ] Quality calibration is deactivated

If I scan a picture sometimes the scanner stops while scanning:

`----

Scanner stops. "Recieving RGB data for 'bild.pnm" hangs. No process.

but 1 min later after plugging the scanner from the usb-Port off and
then again in I get (with exact the same settings!):

,----[/var/log/messages scanning is ok!]

| Oct 31 14:51:58 galilei resmgr[1288]: disconnect from pete
`----

Mostly no other messages, if scanning fails. Mhm.

I am helpless. Du you have any ideas?
Thanks, at least for reading.
