I had similar problem. The only thing that made it work was shutdown the computer, unplug it wait 5-10 minutes,plug in turn on computer and everything worked, go figure
In the case of this Midiman keyboard, it needs a firmware upload after "cold boot". My guess is, that this sometimes is a bit flaky and only works on second try. I do not think that this has anything to do with the other problem of the continuous stream of usb errors and the recently occuring panic messages afterwards.
I did think about the possibility of the keyboard being in a bad state and did unplug and replug it, but it did not change anything.
I'll try the boot option (Oliver) and the patch (Takashi), but will probably only get to it on the weekend (after all, it's my daughter's PC and you should not disturb teenage girl's operations if you don't want to get into big trouble :-)
