I have an old hpIIcx running on gentoo linux with a 2.6.5 kernel . In order to keep either a Symbios 825a or BT-930 from timing out and reseting I have changed line 283 in sanei_scsi to : static int sane_scsicmd_timeout = 7200; and then with these options set in hp.conf: scsi HP /dev/sg0 option dumb-read (BT530) or option scsi-connect (Symbios 825)
the IIcx makes all the right noises and and scanner moves but the lamp goes off just before the final scan pass and my images are all black. I know that the BT-930 has been a problem in the past but I have also tested with aha3940, aha2940u, and sym53c825a with either the same or even less results. Until about 16 dec 03 the scanner was working fine in both gentoo an win2k with the aha3940 and a few other scsi devices (testing with only the scanner now...). I believe I was running sane-backends-1.0.12-r2 in dec. In testing I have gone back thru all the versions from 1.0.14-pre1 to 1.0.9 (modifying the sane_scsicmd_timeout = 7200 each time) and looking at debug logs from sane, but my scan lamp turns off just before the scan pass an results in an all black image in both scanimage, xsane, and kooka (vuescan segfaults). I have also tested with gentoo-sources 2.4.26 with the same results with all scsi adapters. I have been looking thru the source and looking at debug logs but the code is over my head so far, I still can't tell if the IIcx has broken or if there is a bug. Can anyone give any debugging suggestions, or throw any light on this problem. John Youells
