Rob> I had something similar happen to me and was pulling my hair<br>
|
|
Rob> out, trying to figure out what was going wrong. I finally<br>
|
|
Rob> realised that I had changed the SG_BIG_BUFF size in<br>
|
|
Rob> /usr/src/linux/include/scsi/sg.h to the highest recommended<br>
|
|
Rob> value before I compiled SANE but hadn't re-compiled the kernel<br>
|
|
Rob> after I'd made the SC_BIG_BUFF change.<br>
|
|
<p>
|
|
Rob> Once I re-compiled and installed the kernel with this change,<br>
|
|
Rob> SANE and my scanner work properly.<br>
|
|
<p>
|
|
This is a very unfortunate and annoying problem on Linux.<br>
|
|
Fortunately, this problem will be fixed once Linux v2.2 is out (which<br>
|
|
will have support for /proc/sys/kernel/sg-big-buff). In the meantime,<br>
|
|
always make sure the SG_BIG_BUFF in SANE matches the one used by the<br>
|
|
kernel.<br>
|
|
<p>
|
|
Rob> Now if only I could figure out how to get the GIMP to load<br>
|
|
Rob> xscanimage when I'm logged on as a user, I'd be happy. As a<br>
|
|
Rob> user, I can load and use xscanimage but "Acquire Image" isn't<br>
|
|
Rob> an option on the GIMP "Xtns" menu. It is when I'm logged in as<br>
|
|
Rob> root, though.<br>
|
|
<p>
|
|
GIMP queries a plug-in only when it looks like it's something new.<br>
|
|
What you might want to do is:<br>
|
|
<p>
|
|
(a) make sure all your scanners are turned on<br>
|
|
(b) "touch" the xscanimage binary<br>
|
|
(c) start gimp<br>
|
|
<p>
|
|
This way, GIMP should re-query xscanimage and then it should be able<br>
|
|
to find your scanner (the three steps need to be redone each time<br>
|
|
there is a change in the device configuration).<br>
