Hi all,

I've trying to debug a problem I've noticed with the Fedora 33 Beta, 
that seems to be related to USB ports.

I tried even with the 5.9.0 kernel from the rawhide / fc34 tree, but 
the same problem occurs.

I've added an example dmesg from a boot with USB problems, and I've 
noticed that systemd-analyze blame shows:
47.297s dracut-initqueue.service

I notice that when I get this issue, on booting, the BIOS will init all 
the USB devices, and the light on each USB port on my hub comes on 
together. When the kernel boots, all the lights on the USB hub goes off 
and then either don't light up at all, or there is about 5-6 seconds 
between each port coming online.

The system is a Ryzen 2700x with an MSI X470 GAMING PRO CARBON 
(MS-7B78) mainboard.

I do note that my USB keyboard still works when this fault occurs, so 
it does seem to be something specific to either that controller, or the 
USB hubs attached (or both).

Where abouts do we start with something like this?
