I'm probably "fixing to show my ignorance" but the whine is coming from the computer hard drive through the Fast Track Pro. I believe it is a grounding issue between the computer and the Fast Track. I can disconnect every thing and the minute the USB cable contacts the Fast Track you get the whine along with the slight "growl" when the mouse is moved. I'm pretty sure it's the USB ground loop issue. I'm not aware of an any way to ground the Fast Track so here's my question (at last).
The Fast Track Pro has a external power supply for use as a stand alone unit. Is there any way to turn off the USB power from the computer through the USB to the Fast Track and use the grounded power cord to power the Fast Track Pro?
Would I fry everything if I used the power supply cord and the USB together?
