Can someone please help me with this issue? Whenever I try to run configurable USB loader, it tells me that the device is not responding. I tried this on both my usb flash drive and external hard drive, but neither works. I already did the cIOS stuff (56 to slot 249, 57 to slot 250, and 58 to slot 251) My hard drive is is a seagate momentus 7200 (250 GB) in some external hard drive case manufactured by Sabrent (IDK the product number). It's formatted to NTFS. My flash drive is some cheap, flimsy, aluminium+plastic 8 gig one manufactured by PNY, and I have no clue what the product number is. It is also formatted to NTFS. I tried all the ports and none of them work. For some reason though, plugging my HD into the top port on the back side of the Wii U makes cfg lag really bad, and in the end, it still says that it couldn't recognize the device.
