this is the wrong way to do this, please don't do it just yet.
ok, the other two changes look fine.
This disabling is fine if the kernel can later re-enable, but I doubt the
kernel will do that. We need a way to make this usb enable/disable visible
at configuration time, so people can turn on/off as needed, unless usb2.0
on the 8111 NEVER work. I am willing to guess it will work someday, and
this built-in disable will come back to bite us.
