I went to the m-audio site to download drivers for the Midisport 1x1, and it says that Vista 64bit (SP1 and 2) don't need drivers, they're class compliant. However, windows can't recognize it without a driver (all it recognizes is a "unknown device", when it should apparently be a "USB Audio device" (apparently vista groups midi as "audio"). Any ideas, this is very frustrating!
