USB Drive doesn't read in either slot on Wii
So I tried loading SSBB (which I own) on my Wii using Wiiflow, and it did it's magic. But for some reason, it crashed back and said I didn't have any games avaliable. I tried to switch to the USB1 partition, but it wasn't there. So I tried the 2nd USB port, but that didn't work either. I tried USB GX Loader but that ALSO didn't work, even after so long. WBFS Manager still reads it fine on my computer and I don't know why it doesn't work on my Wii. Please help ASAP!
EDIT: I have a Black Wii installed with DOP-Mii, BootMii, PriiLoader, and it's running 4.3u. The USB drive is a Kingston.
