Good question.   Here's the complete usb device list.   You can see that
the hub in the keyboard attaches to uhub5 which is on usb1 which is one
of the uhci companion controllers.

ehci0 did get a "wrong number of companions"; it has 2 actual vs 3
expected, whereas ehci1 has 3.

I am not sure the xchi controller works (it's on an addon card,
installed under windows before I got the hardware and promptly conducted
an exorcism).

I will try the xhci unless I figure this out before I get to that test.
