Thanks for the great guide! I've got USB Loader GX working now. I am using a 128 GB Sandisk Ultra Fit flash drive. This only works on the rear top USB port. If I try it anywhere else, USB Loader just sticks on "waiting for USB". If I keep it in the top rear port and want to add a regular USB hard drive for Wii U backups, do I need to have the Y-cable for that one wrap around so one plug is in the back and one plug is in the front?
