Public bug reported:

[Impact]
USB storage can be stuck in USB reset loop after reboot. More reboots
don't help the situation, unless it's re-plugged.

[Fix] 
Power cycle USB ports on system shutdown/reboot.

[Test]
The USB storage survived 300 times of reboots, and it works under each
reboot cycle.

[Where problems could occur] 
One potential problem I can think of is S5 WoL over USB ethernet. Since
the port power and its associated ACPI power are turned off, WoL may
stop working, if WoL over USB is a thing.
