Hi Henning, after experimenting with linedistance-fix and both, very large and very small buffer sizes, I give up on mustek.conf and approach you with this tricky problem: When hooking up my ScanExpress 12000 SP Plus to an Adaptec APA-1480 Cardbus U-SCSI controller I get ugly horizontal lines in my color scans for resolutions exceeding 300 dpi. Here's the inquiry log: [sanei_debug] Setting debug level of mustek to 255.

On my webserver you may find some example scans with accompanying debug logs for your analysis: * scanimage --mode Color --resolution 288 -t 150 -y 25 -v http://www.lsweb.de/images/sane/scan288dpi.log http://www.lsweb.de/images/sane/scan288dpi.jpg (works) * scanimage --mode Color --resolution 360 -t 150 -y 25 -v http://www.lsweb.de/images/sane/scan360dpi.log http://www.lsweb.de/images/sane/scan360dpi.jpg (screwed) * scanimage --mode Color --resolution 360 -t 150 -y 25 -v=20 http://www.lsweb.de/images/sane/scan360dpi_8MB.log http://www.lsweb.de/images/sane/scan360dpi_8MB.jpg (bigger buffer, but=20 still screwed) By the way, when hooked up to a Symbios Logic 53c875J controller there is no striping to be seen, so there seems to be some problem in conjunction with the APA-1480 (rev 03) hardware or the aic7xxx driver: Adaptec AIC7xxx driver version: 6.2.36 Adaptec 1480A Ultra SCSI adapter aic7860: Ultra Single Channel A, SCSI Id=3D7, 3/253 SCBs Allocated SCBs: 5, SG List Length: 102 <snip> Target 6 Negotiation Settings User: 80.000MB/s transfers (80.000MHz, offset 127) Goal: 3.300MB/s transfers Curr: 3.300MB/s transfers Channel A Target 6 Lun 0 Settings Commands Queued 13152 Commands Active 0 Command Openings 1 Max Tagged Openings 0 Device Queue Frozen Count 0 Hopefully you can see the pattern in there...
