Asus Prime A520M-K AM4 Motherboard has severe USB stutter problem. On-board USB headers which are directly connected to CPU are the only ones that works well but not the USB ports are at the back of the motherboard.
Keyboard and Mouse freezes during gaming or any high load activity such as Video editing, also my USB sound card crackles at those ports.
Asus should provide a BIOS update for the problem.
