I recently enabled the "USB 3.0" option in the BIOS of my notebook.
This transforms two of my USB 2.0 ports into USB 3.0 ports -- I'm
already a little leery of it in that regard. When I boot, I see
xhci(4) attach. However, when I plug in a device (such as my HTC
phone), I see the following:
xhci_do_command: Command timeout!

I'm looking for some hints on where to start looking/hacking, or what
further information may be useful (and where to get it). Again, I
have to assume that since XHCI is an option in the BIOS, this must be
some quirky piece of hardware I'm working with. Oh, and, I guess I
need to know what I'm looking for when I try to identify the actual
hardware (usbconfig?).
Also, I tried and failed at this again with the following changes
(gleaned from HEAD):

There seem to be other changes made as well, which I haven't had the
time to try. Some of these changes are stated to be MFC'd -- will
they make it into 9.0-RELEASE (or a Release Candidate for testing)?
A few examples:
