I can't really set it up that way since my gamecube adapter is hooked up to the front ports. Looking at the thread history it seems that another user had the same issue as me but he has resolved it? I checked and my microsd card plugged into the usb adapter is formatted to fat 32 mbr
UPDATE...
Hi I am currently using uStealth with my vWii (Micro SD to USB Adapter) and 2TB HDD External Hard Drive w/ Power Supply for Wii U.
I am also using the latest version of USB Loader GX r1272
I have the vWii MicroSD to USB Adapter in Port 0 of my Wii U and the 2TB HDD in Port 1 of my Wii U.
