I have a Mac running OS X version 10.4.11, and my My MIDISport Uno 1x1 input was working fine until a couple of days ago. The MIDI Input for my Garage Band and Finale programs was working fine, but then for some reason both programs stopped recognizing this input. I tried running tests on the Mac's Audio MIDI Setup, but that program isn't reading a signal coming into the Mac.

My MIDISport cable when plugged in still has USB light that blinks very slowly, and the MIDI In light blinks very quickly. Playing the keyboard (an M-Audio Keystation 49E) doesn't change the rate of either blink.

I tried a different MIDISport 1x1 cable, and I came up with the same result. I also tried using a different keyboard (a Roland) to see if it might be a keyboard issue, but that wasn't it either.
