Tim, did you reboot after updating your kernel?
Can you also post the output of
ls -l /dev/bus/usb/*/*
sudo /usr/lib/cups/backend/usb
and post the result here?

Scott, are you sure that your 12.04 live CD is completely up-to-date?
You must have the kernel 3.0.0-13 or newer and CUPS 1.5.0-11 or newer.
If this is not the case, do a system update in the live session running
the following commands in a terminal:
sudo apt-get update
sudo apt-get dist-upgrade

completely updated. Usb printer now detected and I was able to set it

Scott, you will most probably need both the kernel update (3.0.0-13) and

Scott, the new CUPS package does not require the new kernel, but there
is a total of probably three USB printing bugs in the original Oneiric,
one fixed by the kernel and two fixed by my CUPS package. So if you want
to avoid rebooting your system, you could start trying with the CUPS

Hi,
I tried this new package and my Canon ip4500 was recognized and installed
immediatly when I plugged the usb : until now nothing happened (I haven't add
the usblp kernel module). So it works. Thanks for the job.
Now, for me there is still the bug
Thank you for your testing and great that it is working for you. This
patch I have uploaded to Precise and proposed as an SRU for Oneiric, as
a fix for bug 887094 and bug 872483. Probably this bug is a duplicate of
one of these (but I do not know which one). Please subscribe to bug

I got our Brother DCP-8045D to work by adding usblp to /etc/modules
and then using parallel:/dev/usblp0 as the URI (the deprecated way of
doing things!).
Simply upgrading to 3.0.0-13 didn't help.

Chris, thanks for your suggestion - the usb printer is detected and

However, it is an MFC with a scanner. The scanner seems to be detected
now, but I get an error message Failed to open device
