hextwelve.

lewurm & theStack have released hextwelve.

hextwelve is a simple Host Controller Driver for both Wiis OHCI controllers, based on Team Twiizers mini/ppcskel (aka BootMii; since all hardware can be accessed directly from the PowerPC due to the AHPBROT hack, we just built on ppcskel and didn't touch any MINI code). As the original goal of the project is just to faciliate the (IOS-independent) usage of an USB keyboard, it currently supports only control and interrupt transfers, which lays the groundwork for supporting other HID class devices as well.
