Ryzen wake from sleep keeps USB off for a while

[IvanE747]

Hi,

 

I got MacOS working my Ryzen system, except that when waking up from sleep my USB peripherals will stay off for around 10 seconds.

 

When I wake up the computer, the USB peripherals stay off for about 10 seconds while I see the desktop login screen. About 10 seconds later my monitor goes black for a second or two and all USB devices power up. I always find that any USB flash drives are ejected after this.

 

I do not have the DummyUSBEHCIPCI or DummyUSBXHCIPCI kexts loaded.

 

Thanks.
