Gamecube Adapter OS X Support

[fluteflute]

I'm new here, so sorry if this is in the wrong section, but I was wondering why Dolphin doesn't have OS X support for the Wii U Gamecube Adapter. Is it a matter of lack of demand, driver issues, or some other compatibility issue? (I'm really curious, so feel free to be as technical as possible.)

It is a driver issue as the libusb driver does not work on OSX with HID devices.  Under OSX, an unofficial kext can be installed to get the adapter recognised as a controller: https://github.com/area/wiiu-gc-adapter-osx

Isn't libusb in C? Why doesn't it work with OS X?
