I'm also experiencing this bug on Ubuntu 9.10 with kernel 2.6.31-16-generic, using a standard PS/2 keyboard via USB adapter. Can attach system logs etc if wanted. Unplugging and replugging the keyboard usually sorts it, but it's a bit annoying!

Sorry for replying to myself here, just thought I might mention that this machine has been continuously upgraded from Intrepid or so, and I had no problems with the keyboard until Karmic. I notice that the original bug 435235 mentions it occurring in Jaunty too, but that was not my experience.

[MatthijsNL (matthijs-wolthers)]

Same issue here. Never occurred before Karmic. Maybe a crazy thought, but might it be that udev kind of overwrites the keyboard when trying to add a printer on every available USB-port? I don't know how to check that myself.

It's a rather annoying issue indeed, and I fear that my keyboard-plug and USB->PS/2 converter will get damaged by abusing them like this.
