My friend has a TvC Fight Stick and he hates using pad so I showed him the Mayflash Wii to USB item and he said it doesn’t work on PS3 (I thought it did?) He said the problem is the buttons aren’t mapped correctly. Here’s the stick:
There is no actual fix. the ZL and ZR buttons do no respond and there no Home button.
Other than that the adapter works fine, I suggest is a PCB swap or buy a stick thats meant for your system
