<P>
Duncan/Oliver and others,
<BR>
<P>Thanks very much for your responses.
<BR>
<P>I finally got my acer prisa 620 usb working. I had to make the following
<BR>
changes to the sane source code. I'm not a C hacker so please let me know
<BR>
if these are incorrect.
<BR>
<P>My system is an iMac running Linux for PowerPC and these changes have only
<BR>
been tested on my machine. Kernel version 2.2.17pre10 with the usb-backport
<BR>
from 2.4.0-test2-pre2.
<BR>
<P>1. File: backend/snapscan-usb.c Line 196
<BR>
<P>- semctl(sem_id, 0, IPC_RMID, 0);
<BR>
+ semctl(sem_id, 0, IPC_RMID);
<BR>
<P>2. File dll.conf:
<BR>
<P>Removed all lines except snapscan.
<BR>
<P>With the supplied dll.conf I kept getting a segfault with no debugging
<BR>
output with SANE_DEBUG_SNAPSCAN=255
<BR>
<P>3. File snapscan.conf
<BR>
<P>scsi AGFA
<BR>
scsi COLOR
<BR>
scsi Color
<BR>
/dev/usbscanner
<BR>
<P>Once again thanks to all who responded. I have no idea how to submit these as
<BR>
patches to the 'sane' source code.
<BR>
<P>Ramprasad
<BR>
