And here is the list of files that are installed by that package:

http://packages.ubuntu.com/precise/i386/linux-image-3.2.0-23-lowlatency-
pae/filelist

Two observations: there is no module "usbcore.ko" for this kernel, but there 
is one named "snd-seq-midi.ko". You may check if the file is missing in your 
machine, or it is corrupt. 

Another easy verification that you can do is: start the machine with a live 
CD/DVD disk, checking lsmod before and after you plug the keyboard.

Beware that the module file name is "snd-seq-midi" (with "-"), but lsmod 
prints "snd_seq_midi" (with "_").
