Worked OK in Breezy, in Hoary, in Warty, in RedHat 7.3 and still works if I reboot into Knoppix 3.4 Live. In Dapper, it's recognised as a USB device, and all the sane command line commands seem OK, but Xsane and iscan both fail to send commands to scanner - it just sits there. < kiwigander> xsane starts, but when I click on "scan", it greys out for 30 seconds or so, then the window "Error: Could not send command to scanner" comes up. < kiwigander> pascal80: I've just run scanimage and get scanimage: sane_start: Error during device I/O < kiwigander> xsane behaves identically whether I start it from a Gnome menu or from a terminal. Failed to start scanner: Error during device I/o. < kiwigander> xsane uses the stock epson backend (with all lines commented out except "usb") and iscan uses the epkowa backend (with all lines commented out except "usb").
