The USB Gecko is a Wii/Gamecube development and hacking tool which connects to the USB port of the computer, and to the GameCube memory slot of the Wii. It can be used to upload homebrew, to use your computer as a remote terminal under Wii Linux and as a remote debugging tool. For more information see the USB Gecko homepage.

To code computer side usbgecko application you need :

For Win32 : API DOC

For Linux : API DOC

Hardware

The usb gecko is a two step converter to convert EXI<->serial<->usb. It is a fancy serial port. All the fun is provided by software. No, the EXI interrupt is not possible to trigger from the PC.

-I have started a Linux application, all seems ok, except the ftdi_read_data that always return 0 :/
