Spotted by DualShockers , the Wireless Adapter is listed with a "CUH" code, which has been used for all previous PS4 certifications.The image above - and power specifications in the listing - point to a USB device. It's also explicitly a Bluetooth device, one that closely matches the transceiver inside the PS4 console itself to connect to its DualShock 4 controllers.While key parts of the listing are being kept confidential until 2017, the most straightforward assumption is that this is an official Sony dongle to be used in connecting PS4 controllers to PC.
