Looking again at the problem, it looks like probe_scanner() gets handed an
intf->altsetting->endpoint arrawy where
(intf->altsetting->desc.bNumEndpoints -1) endpoints have actually been
copied. On the other hand, lsusb seems to see the complete picture.
Hotplug loaded all three [ehu]hci-hcd.o modules; UHCI is the one being used
(I can't unload to try an alternative one, if such thing still exists; I get
an immediate panic). lspci output follows.
