After upgrading udev and the kernel from Ubuntu 12.04 to Quantal (linux-image-3.5.0-5-generic 3.5.0-5.5), USB devices no longer work. For example, I am now typing this on the built-in keyboard of the machine (ThinkPad X220) but the attached Microsoft USB keyboard doesn't work. Nor does the attached USB mouse.
When I look in syslog I see that the devices are detected. For example, on plugging in the keyboard the following messages appear.

(I first tried apport-bug but it fails with a networking error even though I have Internet access, as you can see.)
