First of all, I want to thank all the developers for a great package that<br>
|
|||
|
|
has freed me from the last dying gasps of Windows. I have a problem with<br>
|
|||
|
|
my Umax S-12 and hanging scans. It happens at random times during a scan,<br>
|
|||
|
|
and sometimes not at all - it probably occurs in about a third of all<br>
|
|||
|
|
scans. The scanner will hang, along with the rest of the SCSI bus. The<br>
|
|||
|
|
output of scanimage with SANE_DEBUG_UMAX set to 128 follows:<br>
|
|||
|
|

|
|||

<p>
|

|
|
It looks like there should be another read_data_block here, but there<br>
|
|||
|
|
isn't. Everything comes to a halt. I kill the scanimage program, but<br>
|
|||
|
|
nothing happens. I usually can try to read something from my Jaz drive and<br>
|
|||
|
|
that will reset the bus and allow scanimage to die and cancel the scan<br>
|
|||
|
|
properly. It's happened in all SANE's since 0.66, including 0.68 and 0.67<br>
|
|||
|
|
with the umax patch. Is this a known problem? I'll be happy to give any<br>
|
|||
|
|
more info you need.<br>
|
|||
|
|
<p>
|
|||
|
|
While I'm at it, i have an xscanimage nitpick dealing with the preview<br>
|
|||
|
|
window. With it open, sliding the resolution slider (for example) gets a<br>
|
|||
|
|
lot slower and it looks like the preview window is being redrawn with each<br>
|
|||
|
|
incremental movement of the resolution slider. Is this necessary? I can<br>
|
|||
|
|
see redrawing for the window sliders since you have to redraw the<br>
|
|||
|
|
rectangle, though. Also - the preview window refuses to close, also since<br>
|
|||
|
|
0.66, but I suspect these might be more GTK's problems rather than SANE's.<br>
|
|||
|
|
<p>
|
|||
|
|
All pertinent info I could think of:<br>
|
|||
|
|
<p>
|
|||
|
|
Pentium 90, 80mb ram<br>
|
|||
|
|
Redhat 4.2, Linux kernel 2.0.32<br>
|

|
|
BusLogic BT-948 SCSI card<br>
