Somewhat similar story with my LS-2000. I modified it to accept the<br>
|
||
string "LS-2000" and it seems to recognize the scanner, but the<br>
|
||
machine locked up hard when I hit "Acquire preview". With the<br>
|
||
autofocus code commented out and no slide inserted it would scan a<br>
|
||
zero by zero image, but with the slide inserted xsane died with a<br>
|
||
floating point exception(!) When I rebooted into Windows I got a<br>
|
||
message that the autofocus operation had failed, so I power cycled the<br>
|
||
scanner. I'm not fully convinced that inserting the slide really<br>
|
||
affected what was happening, I should try all this again.<br>
|
||
<p>
|
||
Of course, I'm assuming that the LS-2000 has the same command set as<br>
|
||
the LS-30 just because they look exactly the same. This may be a poor<br>
|
||
assumption.<br>
|
||
<p>
|
||
Any tips on how to debug back ends? It seems like you can't compile<br>
|
||
with -g because then inb and outb are undefined. And what's<br>
|
||
find-scanner?<br>
