I've often found Vista drivers are most successful with Win 7 if they are available. I've had USB Midi cables recognized automatically, though .. It's worthwhile looking in the Device Manager under "Sound Controller" section, and see what shows up when you plug it in... Maybe even hit "Scan for new devices" if you don't see it.

Looks like Vista is as high as is supported.
