1400 + MSI B350M MORTAR + RX460 + windows 10
After I eject USB devices successfully, the USB ports do not power down, and the USB driver still spinning.
I have reset my OS but this problem does not solved.
I have tried to start in safe mode, and this problem is gone away.
I have tried to start without any boot applications and only load basic system services, but this problem still appear.
I have tried to delete all the drivers but AMD, but this problem still appear.
I have asked MSI's after-sales service staff, but they don't know. (I have turned off the switch of wake-on by USB and enable the option of ErP Ready)
I asked my friends who use Ryzen platform, and they said they have the same problem, but they don't think this is a big problem.
I have no idea to solve this "problem".
