It's not showing up in the cards list above, which seems to indicate that the 
snd_usb_audio module isn't loaded, or you've forgotten to switch the keyboard 
on.  Have a look in lsmod to see if the module is showing there.

If not, load it with.
sudo modprobe snd_usb_audio

Then see if the keyboard shows up in the cards list.
