So a guy named Xtreme2damax is currently having the same problem as me. Let me just quote what he says,
Currently I'm on IOS58, using a 128GB usb stick, and on 4.3U. Strangely, USB Loader GX can read it just fine.
Any help? I'll link the original post here. Thanks.
WAD Manager, Wii64 and Desmume cannot mount my USB. When I try, Desmume just shows me with an error saying "cannot mount usb" and brings me back to the homebrew channel. Homebrew Browser gets stuck in a loop between Cannot find SD card (i don't have one) and Cannot mount USB. WAD Manager just shows me an error.
