I am currently using Dolphin 5.0, and I recently bought two Cirka's USB Gamecube controllers. When I plug them in, my computer recognized them as separate controllers. When I try to config them in Dolphin, they appeared to have the same path and only one of them work when both are plugged in.
I tried config one, unplugged it and config the other, but Dolphin still gave them the same path(DInput/0/NGC USB Gamepad)
So in summary, I got two USB GameCube controllers from one company. My computer recognized them as separate controllers but Dolphin does not. And thus, I can only play with one controller instead of both since Dolphin can't tell them apart.
