OK, git bisect has rendered its verdict:
d35e70d50a0641ebc1502fd343bef9b4011ada27 is the first bad commit

usb: Use hub port data to determine whether a port is removable
Hubs have a flag to indicate whether a given port carries removable devices
or not. This is not strictly accurate in that some built-in devices
will be flagged as removable, but followup patches will make use of platform
data to make this more reliable.

...and, indeed, things do seem to break right there.
I assume there's something funky about the (oldish) USB bluetooth dongle
that came with my keyboard that interacts badly with this patch. Matthew,
is there anything I can do or tell you to help figure this one out?
Thanks,
jon
