USB problems after r316423 (LLVM-4.0)

[Kevin Oberman]

USB on my system (Lenovo T520-Cougar Point chipset) fails to initialize. I
have reported this in
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218513

Can others running 11-STABLE at or after r316423 confirm the operation of
USB ports? It seems unlikely that I am the only one seeing this as my
system is pretty vanilla, but I have seen no other reports.

If you have such a system, can you either confirm that USB is working or
test by plugging in any USB device and seeing if it shows up or check
/var/run/dmesg for the errors reported in the ticket?

I am running GENERIC except for SCHED_4BSD. (I tried SCHED_ULE with no
change.)
CPU: Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz (2491.97-MHz K8-class CPU)
  Origin="GenuineIntel"  Id=0x206a7  Family=0x6  Model=0x2a  Stepping=7
Other details are in the ticket.

Thanks so much.
