It's just a generic HID device. Just to be sure I went to the list of all USB HID devices and activated everything - no luck. I wonder what's going wrong there. The enumeration does work, the device gets detected and even added as a HID device to the system. Just pressing keys doesn't help. Weird.

Oh, nice. Maybe I'll just get one of those and not care about that USB keyboard.

I'm pretty sure the Arm-hack doesn't work on my Wii, so I'm out of luck there.

Why exactly is that a requirement anyways? IIRC there's a way to give full access to all device's MMIO regions to the PPC.
