As root, I obtain the following : Here, you will find what the plustek backend told me, with SANE_DEBUG_PLUSTEK set to 10 : http://pastebin.ca/1949440 Here the log for sane-usb with SANE_DEBUG_SANEI_USB set to 10 : http://pastebin.ca/1949441 I also paste the log here for the plustek backend. : " [sanei_debug] Setting debug level of plustek to 10.
