USB Universal - No Serial - No Bus - No leave the USB alone, seriously, that's my advice

  Well, the issue is that Xbox controllers are already USB, they just have a special end.

    ...and they conveniently put those quick-disconnect dongles on the end so you can make your own normal dongles It looks like some people have already written Windows drivers, if you wanted to experiment you might look at writing a userspace driver for Linux. It's kind of strange that they built something custom instead of just implementing it as a couple standard HID devices with an internal hub.

      It's kind of strange that they built something custom instead of just implementing it as a couple standard HID devices with an internal hub. Depending on the USB chip/microcontroller used, it can be a lot easier to just toss in a bunch of vendor-specific requests instead of adhering to all the requirements of an HID-class device (though I haven't analyzed the Xbox controller itself, so I don't know if that's what was done). Also, there's no need to use an internal hub, as a single USB device ("function" in the USB spec, IIRC) can have multiple "interfaces" that implement different (or the same) classes, such as HID, CDC, mass storage, or vendor-specific.

      they do work fine once you replace the ends, I did it with mine
