Make sure the hub and all USB devices are connected at power-on,
otherwise, try a different hub.
I have used the Logitech mouse/keyboard combos (various ones with a
single USB receiver) as well as powered USB hubs successfully. The
hub I typically use is built-in to various Dell monitors I picked up
at surplus for use with the BBB. I honestly haven't seen much trouble
with the USB ports (as long as you're not trying to hot-plug), but
maybe I've just been lucky.
Regardless, the Machinekit 3.8.13-xenomai kernel should support the
same USB devices as the standard 3.8.13 kernel, so any USB tips or
debugging help (for the 3.8.13 kernel) should apply.
...or if you're feeling particularly adventurous, you could work on
trying to port to the 4.x kernel series (different cape manager and
PRU support).
