I've searched high and low on here trying to find more information on why only the bottom USB port works for USB Loader GX. I believe a while back I had it plugged into the top one but then I ended up doing something, it's been quite a while and then all of the sudden it was only the bottom that worked for USB Loader GX. I remember reading something about it but if anyone could help me out on resolving the issue I would really appreciate it. Thank you, happy holidays
