I have the same problem, and yes, if I plug it in after boot
the mouse attach and is usable. But if plugged before boot
the port is completely disabled (maybe all the ports).

There's probably some differences in the detection while
booting and after boot.

I'll do that this week-end if someone hasn't tried yet. I'll
