Glad to see you back Jskyboo, the changes are a welcome and in some cases needed additions to the arsenal of Wii hacking weapons which is WiiMod.
Just tried 3.1 with DisableSetAHBPROT=1 to see if it fixes USB, I don't see that you updated anything related to that anyway but just wanted to let you know that so far 2.7 is still the only one that works with my USB lol, I know i sound like a broken record sorry but maybe you can trace down the changes that broke USB support for some of us somewhere along the way, in turn I won't need to use any other wad manager in my opinion
Again glad to see you out here again man and hope to see more from you soon.
Edit: I do use 3.0 and now 3.1 with my SD card by the way just not USB.
