This is a USB wireless gamepad in the PlayStation style, which seems to
be mostly available in Japan. (Amazon: https://amzn.com/B01MXY05W0) It
complies with XInput.

Bug: b:159368181, chromium:1096754
Test: Connect the gamepad in "X" mode, load gamepadviewer.com, and check
that pressing buttons and moving axes is correctly reflected on-screen.
