M-Audio Keystation 49e OS X Yosemite support

Suddenly when updating the operating system on my computer from OS X 10.9 to 10.10 my keyboard stopped working. I googled in vain after a solution then but now it seems like someone found a workaround over at the M-Audio forums. Yet again I can use my Keystation together with Garage Band.

You are supposed to go into the “Audio MIDI Setup” and create a new MIDI “configuration”.
