I am having the exact same problem https://forums.dolphin-emu.org/Thread-360-controller-not-detected-when-configuring-wiimote-emulation?highlight=controller+not+detected had.
Dolphin will not detect my wired xbox 360 controller.
My 360 controller has drivers installed manually, it works with steam games, and windows detects it just fine.
I'm using Dolphin 5.0 x64 with no tweaks. Dolphin runs games fine using my keyboard.
I've tried refreshing, rebooting, reconnecting, and I've had this problem for months.
