Message posted by Peter Buhr <peter.buhr@...>: When I wake my iMac from sleep mode, I cannot use certain USB MIDI devices any more (Korg microKontrol + Evolution MK-249C keyboard). They are greyed out in the Audio Midi Configuration. Is this an Mac OS 10.4 bug or related to the Korg and Evolution drivers?
