But I can probably look at the hardware and driver aspects of it.  My hardware is very simple, a direct connect between the 5650 and a single USB plug on the chassis. There's a similar platform I have someone else working on that has a 4-port hub too, to look at "some day".

That's the DWC_OTG driver.  It's BSD-licensed (or nearly so) in Octeon
Linux, but probably GPL tainted in at least a few places.  Someone was
working on porting it to FreeBSD, but I believe they abandoned that
approach in favor of writing a driver from scratch.  It should be easy
enough to port to FreeBSD, although I understand that Elite USB
Hackers probably wouldn't find a from-scratch driver very difficult
given the amount of code-as-documentation that's available in that
for.

Good luck!
