I would like to have you informed about what I found out, see https://bugzilla.novell.com/show_bug.cgi?id=127524#c17 For some all-in-one devices (like the Epson Stylus Photo RX420) which have also a cardreader unit included there is additionally the "usb_storage" kernel module which gets in conflict with SANE. In particular for me the "ignoring EBUSY from USB" in SANE didn't work when both "usblp" and "usb_storage" are loaded but it works when only "usblp" is loaded. At least for me for printing and scanning "ignoring EBUSY from USB" is a good workaround but it seems to be not the final solution. >From my point of view the problem lies somehow deeper in the USB system (or how the USB system is used) but I am no USB expert so that I don't know at the moment what exactly causes the conflict and what a clean solution would be. Olaf, regarding Iscan: The Iscan sources contain sanei/sanei_usb.c and this must also be changed so that the epkowa backend also "ignores EBUSY from USB", see http://cvs.alioth.debian.org/cgi-bin/cvsweb.cgi/sane-backends/sanei/sanei_usb.c.diff?r1=1.42&r2=1.43&cvsroot=sane Kind Regards Johannes Meixner -- SUSE LINUX Products GmbH, Maxfeldstrasse 5 Mail: jsm...@suse.de 90409 Nuernberg, Germany WWW: http://www.suse.de/
