ScanMaker V310 (parport) works fine both gray & color; but if any of the /shadow/midtone/highlight/ options are changed from their defaults (mode=Gray) then scan fails. Both scanimage and xscanimage fail the same way...
sane-backends 1.0.13; microtek2 v0.95; Debian distribution. kernel 2.4.18; using modules ppscsi + onscsi. "scanimage -d microtek2:/dev/sg1 --mode Gray --resolution 150 \ --no-backtracking=yes --shadow 80" From debug output it appears that process starts normally, i.e. the same as successful scans, and proceeds thru "calculate_sane_params" and "scsi_wait_for_image" before infinite Busy loop times out. ---> sane_start --> scsi_read_image_status = Busy (forever) until retry count expires. Are shadow..highlight not supported in ScanMaker V310? Is this a known issue in microtek2 backend? If not, what debug dumps would be most helpful for a bug report? ...Gene...
