Comment 94 for bug 872711

My Canon MP630 printer was working just fine in Ubuntu 11.10 64-bit until about a week ago. I discovered it had stopped working, yesterday. I tried to reinstall the printer, but I cannot get it added back. It is no longer detected by the printer add dialog or even by lsusb.

I wonder if the upgrade to 3.0.0-16 killed it?

Since it is completely undetected, none of the suggested troubleshooting procedures produce any helpful output.
