I have a ASUS PN51 S mini pc that has two xhci devices. One from AMD, and other
from ASMEDIA. The one from ASMEDIA have problems when resume from suspend, and
keep broken until unplug the  power cord. I use this kernel parameter:
xhci-hcd.quirks=128 and then it works ok. I make a path to reset only the
ASMEDIA xhci.
