So, I went back to SCSI which works still fine. SCSI driver is loaded during boot, and a small script adds an entry to /proc/scsi/scsi before xsane is called (scanner is usually switched off). > > Sorry for not having better news. Thanks, Klaus, Yes, I compiled the kernel without scanner support (not an option in 2.6.11, anyway). I've tried all sorts of settings in umax.config, with no success. I finally gave up on USB, and procured a SCSI card (Adaptec AVA2904, based on the AIC7856 chip set). This uses the same AIC7XXX driver as my main embedded SCSI disc interface. Now at least I can access the scanner, and, in part, it works; I can even get a scan out of it. The only problem is that it takes about 40 munutes hour to do so, apparently getting shading data; 64 lines of this, each taking about 30 secs. Could still be a SCSI problem, I guess. I had to get on with other work, and have plugged it all back into my XP <spit> box. Scanner Access Not Easy, in my experience <sigh>. I'll give it another go next week, but I don't really know where to go from here. Sad. -- Tony van der Hoff | mailto:t...@vanderhoff.org Buckinghamshire, England
