Argh, my 2480 is changing to 5.5cm by 7.5cm (judging from the preview window). Debug log attached. BTW, is this correct: $ sane-config --version 1.0.16 I installed today's cvs over 1.0.16; I did 'make uninstall' first. Please let me know how I can be of help. -- Miguel Bazdresch -------------- next part -------------- A non-text attachment was scrubbed...

When I look at udev there are entries for a usbscanner in 50-udev.rules. I noticed the permissions are 644 so I'm going to try changing them to 0666. If I add my CX6600 (oxo4b8 0x0813 to the epson.conf and uninstall iscan do you think it will work? is it better to run iscan-free? I don't care anymore if I use Iscan and epkowa or what as long as I get something working. I tryed the suggestion of disabling my usblp, but it did not help. How do you switch to udev and disable hotplug when novell say hotplugs not used? I see no scanner created for my CX6600 but the printer and usb disks are. Thanks for everyones continuing help.
