Sorry for the alarm. It actually works now, after <br>
|
|
<p>
|
|
#ifdef NEED_MUSTEK_LINE_DISTANCE_WORKAROUND<br>
|
|
#undef NEED_MUSTEK_LINE_DISTANCE_WORKAROUND<br>

#endif<br>

in my working sources. My first configure after obtaining sane was<br>
|
|
with --disable-ld-fix, but as scanning didn't work at all, I<br>
|
|
reconfigured for debugging and forgot this.<br>
|
|
<p>
|
|
The only drawback I notice is speed. Could anybody tell me, what<br>
|
|
is a reasonable size for SG_BIG_BUF? Is it possible to prepare<br>
|
|
configure for profiling ?<br>

This sounds pretty good!! When the code is available, I will report<br>
|
|
success for the 1542 to be included in the man-page.<br>

A Mustek technician (whom I invited to join this list, hope he does)<br>
|
|
told me that PNR as opposed to PNP will not be seen by Win95, such<br>
|
|
that this OS will not mess with it. Initialization is done completely<br>
|
|
by the driver.<br>
