            Bug ID: 218513
           Summary: USB fails to initialize
           Product: Base System
           Version: 11.0-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: rkoberman at gmail.com

11-Stable no longer works with my USB controllers. My old kernel, r314236,
works fine, but my kernel of April 6 (r316552) does not see any USB devices.

Any recent changes to the USB software that might explain this? I will be
trying to track it down by bisecting, but this will be slow die to lack of
time. (Moving in two days.)

I see the following from the boot:
ehci0: <EHCI (generic) USB 2.0 controller> mem 0xf252a000-0xf252a3ff irq 16 at
device 26.0 on pci0

usbconfig -d ugen1.1 reset produced:
