The USB port on the DualShock 4 controllers was primarily designed to charge the device and not to provide connectivity. It wears out rather quickly. If you want to use the controller on a PC I recommend trying to find the "DualShock 4 USB Wireless Adaptor". Unfortunately it has been discontinued outside of Japan for quite some time so you might need to use ebay, et, also it's not exactly cheap. The game supports this adapter directly, no need to fiddle with DX4Windows, etc-
