Reverting /usr/src/sys/dev/bsd/controller to r248085, building and loading just xhci module makes drives appear again. Below are snippets from the log in both cases:

1) I will try to apply this patch on top of 253503. Let me know if I need to revert to the earlier rev -- that would take a little bit more time.

2) ASMedia is not a USB 3.0 controller -- it is one of three umass devices I was doing testing with (USB-to-SATA enclosure). The other two devices are made by Seagate and Western Digital. The USB controller is

xhci0 at pci0:2:0:0:       class=0x0c0330 card=0xffffffff chip=0x00141912 rev=0x03 hdr=0x00
    vendor     = 'Renesas Technology Corp.'
    class      = serial bus
    subclass   = USB

I can try to find different USB controller, but that would take some time.
