Yes, works except for bandwidth budgeting.

I haven't. According to the spec, the code should check this and prevent
it from happening, but it's not implemented, yet.
I don't suspect our code will have any problems with it, but timing
problems may cause some problems.
I do have 5 hubs, I'll test it and see if we have any problems.

14. Didn't have any problems with them.
That includes logical devices (this hub which has 2 serial and 1
parallel shows up as 3 seperate devices).
