Multi-controller USB adapters reports controllers wrongly on Mac OS X
tested 3 different devices:
- EMS Trio Linker Plus II - 1 GameCube port + 1 Dreamcast port + 1 PlayStation port
- Dual SNES Adapter - 2x Super NES ports
- Mayflash GameCube Controller Adapter (PC mode) - 4x GameCube ports
(I think all of them are made by Mayflash)------------
Any of the listed devices show a multiple controllers correctly on Windows but a single monolithic Controller on Mac.
On Windows it shows everything correctly and separated.
On Mac everything works but as if there is a single device with 40+ buttons, 10+ axes, 4+ hats.
with the exception of EMS Trio Linker Plus II, it reports more than one device on Windows no matter the number of connected controllers (including no one).

This is an issue I noticed long time ago, but tested recently and it still persists.
