Issues with usb game loaders (vWii)

[I-need-help-with-wup-wiiu]

I have an issue:
I tried two different usbs for putting games on usb loader gx, and tried wiiflow, but games dont appear on those apps.
I tried formatting to NTFS,FAT32,WBFS,exFat, still nothing tho.
Does anybody know what could be the issue?
P.S. I tried wii backup manager but still no results, even with wbfs format, fat32, etc.

Make a folder named "wbfs" in your drive root. Any wbfs iso should show up.
Keep the drive itself formatted to FAT32 or NTFS, exFat won't work.
Make sure the drive is in the top rear usb port. All the others are incompatible.
