USB MIDI keyboard not responding in Yosemite

[blaqink]

I noticed my USB midi keyboard (M-audio keystation mini 32) is causing Logic Pro x to hang while launching if it is plugged in during launch. As soon as i unplug it Logic loads just fine. The keyboard is not working in Logic or Garage Band. When I reset the Midi drivers Logic pro freezes. Similarly Audio MIDI setup also freezes when launched while the keyboard is plugged in. Anyone else having issues with MIDI and Yosemite?

It's probably down to M-Audio drivers. If you do a spot of googling, you'll find a few grumbles about them not playing nicely with Yosemite.
Unfortunately M-Audio are not too quick at issuing updates in my experience.
Either way, my M-Audio midisport midi interface isn't working in Yosemite either.
I've read of some workarounds, but I think it involved the terminal, which is alien territory for me!
