Reading src/sys/dev/usb/uhub.c (line 150ff):

        if (dev->depth > 0 && UHUB_IS_HIGH_SPEED(sc)) {
                aprint_normal_dev(self, "%s transaction translator%s\n",
                       UHUB_IS_SINGLE_TT(sc) ? "single" : "multiple",
                       UHUB_IS_SINGLE_TT(sc) ? "" : "s");
        }

If you really do _not_ see the '... transaction translator.' message
your additional usb hub seems _not_ to communicate in ehci mode,
right?

Without ehci it works for me, too. ;-)

It could be a usb hub specific problem, though.
I'll try to produce some debug output tonight.
