freebsd stable - Apr 2017 - USB problems after r316423 (LLVM-4.0)

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.

I'm running 11-STABLE r317090 and USB devices work just fine (keyboard,
mouse, memory sticks). I don't see the errors reported in your bug
report, either.

Not sure if it matters, but my system has an AMD/ATI chipset.
pciconf -lv reports the following:
...
ehci0 at pci0:0:18:2:      class=0x0c0320 card=0x83891043 chip=0x43961002
rev=0x00
hdr=0x00
    vendor     = 'Advanced Micro Devices, Inc. [AMD/ATI]'
    device     = 'SB7x0/SB8x0/SB9x0 USB EHCI Controller'
    class      = serial bus
    subclass   = USB

Kevin,

Haven?t noticed anything unusual with USB. Just have tried other things like USB
stick, USB cdrom and USB ethernet, both on USB2.0 and USB3.0 but no issues
