Bug Description
Binary package hint: libsane
Filed on behalf of kiwigander/'Andrew Packer' [amp@219-
< kiwigander> Epson Perfection 2450 Photo. 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").

I have now fitted a computer (AMD-64 running Dapper) with an IEEE-1394 Firewire port, connected the scanner via that interface (it shows up at /dev/sg0) and, after tweaking permissions, xsane works it flawlessly. Another Epson Perfection 2450 Photo user (running various versions of Fedora Core) reports essentially identical behaviour. Therefore, is the problem with the more recent version(s) of libusb, rather than with libsane?
