Servus !<br>
<p>
Sorry for getting on your nerves but color scanning still isn`t possible.<br>
The same old error message "Failed to start scanner: Device busy" is on the <br>
screen after the first pass.<br>
But I have an idea: This message comes before<br>
the carriage has returned. The error occurs when trying to start a second<br>
gray scan before the scanner is ready again. So maybe If you wait a little<br>
bit before starting the second and third pass this problem could be solved<br>
because the carriage gets the chance to return before the scanner is started <br>
again. <br>
The other patch for resolution fix works great: Now I can scan 600 dpi images.<br>
<p>
Another thing: Trying to scan in color mode with xscan is only once possible:<br>
Every time after this xscan terminates with ** ERROR **: sigsegv caught<br>
when I change the mode to color. Maybe this is a problem of my S.u.S.E. 4.4.1<br>
Linux system.<br>
<p>
