|
<P>
|
|
Other people seem to have had a fairly easy time with the 1200S,
|
|
<BR>
|
|
so I suspect I'm doing something silly.
|
|
<BR>
|
|
<P>Anyone got any ideas what to try next, or what to try under gdb ?
|
|
<BR>
|
|
<P>John.
|
|
<BR>
|
|
<P><P>Initially:
|
|
<BR>
|
|
/usr/local/bin/scanimage -v --device epson:/dev/scanner --help
|
|
<BR>
|
|
works (repeatedly).
|
|
<BR>
|
|
<P>If I then do:
|
|
<BR>
|
|
/usr/local/bin/scanimage -v --device epson:/dev/scanner -T
|
|
<BR>
|
|
that also PASSes (scanner whirrs, etc), but only the first time I try it.
|
|
<BR>
|
|
<P>The second and subsequent times, I get:
|
|
<BR>

|

Segmentation fault (core dumped)
|
|
<BR>
|
|
<P>[ it dies in strcmp, in libc ]
|
|
<BR>
|
|
<P>From this state, I can return to the initial, less broken, state by
|
|
<BR>
|
|
power cycling the scanner.
|
|
<BR>
|
|
<P>Explicitly removing, and re-adding the scanner scsi device seems to have
|
|
<BR>
|
|
no effect. (echo "scsi remove-single-device 0 0 2 0" > /proc/scsi/scsi).
