Comment 44 for bug 468701

/I have the same issue with a Canon ip4000 since upgrading to Kubuntu 10.04. It worked perfectly in 9.x, but now it doesn't show up.
I tried running the patch above #21 with
sudo ./cups-deviced-allow-device-ids-with-newline.patch -patch
patching file scheduler/cups-deviced.c
Hunk #1 FAILED at 577.
1 out of 1 hunk FAILED -- saving rejects to file scheduler/cups-deviced.c.rej

Here's the output of the commands above
sudo /usr/lib/cups/backend/usb
DEBUG: list_devices_libusb
DEBUG: usb_find_busses=8
DEBUG: usb_find_devices=12

I'd love to get this working again.
