Hi,
I'm trying to passthrough a USB host controller (2.0 or 3.0) but there
seems to be some kind of problem.
# uname -a

Only the 1:0:0 disk controler is hidden. The two USB controllers, one
ehci and one xhci are not.
Why don't the controllers get hidden?
Is the blackhole_load="YES" still relevant? I tried with and without
that line to no avail.
Is my STABLE version too old?
Luis
PS. Keep up the excellent work bringing
