This is a third-party device that has appealing properties when used as a PC gamepad.

* Standard dual analog gamepad with analog triggers and vibration
* Supports three different modes of communication (XInput mode and two DirectInput modes)
* In XInput mode, pretends to be a genuine Xbox 360 gamepad (exposes the same device IDs)
* ~$20 on Amazon
* Genuine wired Xbox 360 gamepads are getting harder to find

The XInput mode is currently well supported because Chrome treats it as if it were a genuine Xbox gamepad. We should add mappings to better support the other two modes of this device.
