Mayflash/Gamecube Controller Adapter Broken

[Azathoth]

While I can't pinpoint exaclty what day or what patch my mayflash 4 port GC adapter stopped working, it's been nonfunctional for 2+ weeks now. It's defintely a problem within the game itself because the controller(s) I've tested work fine on Dolphin, and windows recognizes it as a proper controller through Vjoy so I'm not sure what else to do. Clean driver installs (and reinstalls) of both the winusb drivers, mayflash offical drivers, and general system updates still have yet to fix it. A friend also purchased a fresh, official nintendo smash ultimate adapter and controller, neither of which work for him either.

Anyone else having this issue?

Same here... controller worked just fine before and since an update, it no longer works.
