I would recommend getting a non-usb version. I've had issues using USB adapters with range and etc.. Not to mention in certain fast paced games like mario kart or smash when using 4 controllers some signal lost or delay happening. Also bluetooth 4.0 is pretty old at this point.

​

I'd recommend this PCIE add in card, fairly cheap but not as cheap as a usb bluetooth adapter. Range is absolutely killer and its bluetooth 5.0 and works great on Cemu emulator with 8 controllers playing Wii U smash.

These are the two things you need....

This is the chip that enables bluetooth

These are the wireless antennas which give amazing range.
