Windows 10/11 aggressively powers down USB ports. This is the #1 cause of error 0x54f.

Error code 0x54f is most commonly associated with a driver initialization failure. While it can occasionally be caused by a faulty USB cable, in the context of ASIO drivers, it usually points to a software conflict—specifically, a corrupted driver installation or a conflict with generic Windows audio drivers.
