I already sent this message 2 hours ago, but it didn't appear on the
|
|
<BR>
|
|
least by now. Perhaps, because of the larger attachment.
|
|
<BR>
|
|
So this time, I put the logfiles on http:

----
|
|
<P>I have an AGFA Snapscan 1212U. The version that doesn't need a firmware
|
|
update (AFAIK).
|
|
<P>Using
|
|
sane-backends-1.0.4.tar.gz
|
|
sane-frontends-1.0.4.tar.gz
|
|
snapscan-20010411.tar.gz
|
|
xsane-0.75.tar.gz
|
|
linux-2.4.3 (scanner.o, usb-uhci.o/uhci.o)
|
|
<P>I finally managed to see my scanner at least. (see attached logfile)
|
|
<P>Now the problem is, when trying to aquire a preview image, both
|
|
xscanimage and xsane crash with a floating point exception.
|
|
<P>According to the debug output and gdb, the problem seems to be that
|
|
p->bytes_per_line is 0 and therefore an exception is raised. (See at the
|
|
end of attached logfile)
|
|
<P>After this the scanner behaves very strange, from not answering anything
|
|
to sending strange identification strings (@ d %!, or something like
|
|
this) and needs to be turned off/on.
|
|
<P>I already tried to switch my usb ports. My logitech mouse is running fine
|
|
on both.
|
|
What is also strange: lsusb says "cannot get string descriptor 1,
|
|
Connection timed out (110)". The message is always somewhere in the output
|
|
of the first usb device. (see lsusb1.log, lsusb2.log)
|
|
<P><P>Any help would be very much appreciated.
|
|
<P><P>regards
