There is a lot of things that suck in USB stack all BSD's are using at the 
moment. This particular one is one of smallest ones I worry about ;).

There is a light though. There is a new USB stack known as HPS or usb4bsd 
under development in FreeBSD. This particular problem is already resolved 
there as well. Also two biggest problems with current stack - sucking 
isochronous transfer support and sucking ugen.

See these for details:

Volunteers to port needed ;P.
