David,
Yes it should just work.. did you set it up on the settings page? and do you have a shuttle Pro 2 or one of the other ones?
Jon,
Yup it works like an MPG every click is at the inc that you have set if you are in Inc mode

if you turn it to fast it will not keep up but it has a good feel..
I think it should work on a non usb2 but I done have one here that I can check that on
