I have a Canon MP250 device. The manpage of the pixma backend states that this device is supported, but when trying to use scanimage, there's no scanner detected.
Test case: Plug the scanner, and check lsusb and /var/log/messages: # dmesg [ 48.452116] usb 1-5: new high speed USB device using ehci_hcd and address 6 [ 48.568240] usb 1-5: New USB device found, idVendor=04a9, idProduct=173a [ 48.568248] usb 1-5: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 48.568255] usb 1-5: Product: MP250 series [ 48.568260] usb 1-5: Manufacturer: Canon [ 48.568265] usb 1-5: SerialNumber: 2A7E97 [ 48.757977] usblp0: USB Bidirectional printer dev 6 if 1 alt 0 proto 2 vid 0x04A9 pid 0x173A [ 48.758422] usbcore: registered new interface driver usblp [ 51.250104] wlan0: no IPv6 routers present [ 60.211879] fuse init (API version 7.16) [ 60.257069] SELinux: initialized (dev fusectl, type fusectl), uses genfs_contexts [ 60.270808] SELinux: initialized (dev fuse, type fuse), uses genfs_contexts # lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 002: ID 413c:a005 Dell Computer Corp.

If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages). # scanimage -L PIXMA_EXPERIMENT=0; SANE_DEBUG_PIXMA=21 scanimage -L No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate).

I'm using Fedora 15, with latest source from git repo: scanimage -V scanimage (sane-backends) 1.0.23git; backend version 1.0.23 (commit id: cbc281c30a3d7bfcc02750cf782a4c8e6efac07c) I want to help to get this fixed.
