A:Answer This is an answer to the other "answer" that asked if it's USB 3.0.
Recapped from my review of this product, This is a very deceiving product as only 1 port is USB 3.0, others are just 2.1 at best and using shared power.
The port on the right is a pass-thru port directly from the PS4's USB port, so it should be USB 3.0. It has full power from PS4, so should not have problem for any USB device.
The 3 ports on the left share the same removable connector behind (so to fit Slim or Pro). The connector has only 5 pins, so it cannot be USB 3.0.
Which means they might only get 100ma per port. So for keyboard and mouse, they should work, but for other device that require more power, those might need to be external powered.
