Hello Denis, I'm new to these mailing lists, so I hope I mail this alright. I had the same problem like you, though before my 3490 I was struggling to make an old canon scanner working with Xsane and learned a bit..
1: look into /etc/sane.d/dll.conf Mine missed an entry to epkowa.conf which is essential for the 3490 according to the iscan installation manual. http://www.avasys.jp/english/linux_e/dl_scan.html (get the pdf) So insert 'epkowa' into dll.conf 2: restart saned: # saned restart 3: now try # scanimage -L I bet it works. Greetings, Imar. ICQ: 11555901 Denis Haskin wrote: Very weird. Looks like what's happening is that the scanner keeps resetting itself (every few seconds) and gets assigned a new USB device number. I thought maybe the problem was I hadn't specified any firmware file, so I got that off the Windows install CD and modified snapscan.config to add it, but hasn't seemed to change behavior. Anybody have any thoughts? Thanks, dwh
