Hi !<br>
|
||
<p>
|
||
The lines below are the "official" delays that are to be<br>
|
||
introduced into the sanei-code to prevent hanging of the<br>
|
||
Mustek 600 II N backend on a fast computer.<br>
|
||
<p>
|
||
The diff was taken relative to 0.74, but I hope it is still<br>
|
||
valid for 1.00+ also. Please include this into the next<br>
|
||
official release for SANE. Thanks !<br>
|
||
<p>
|
||
There is one more patch from Henning Meier-Geinitz <<a href="mailto:henningmg@gmx.de">henningmg@gmx.de</a>><br>
|
||
that I have still not yet tested -- sorry. It is from 14 Apr 1998<br>
|
||
and can also be found in the mailing list archive. But it is<br>
|
||
possible that it works for some scanners and breaks things for<br>
|
||
other ones, so...<br>
|
||
<p>
|
||
Regards, Andreas.<br>
