Do you have any links to some previous USB work you've done? The FreeBSD USB stack is I/O-vectored while the Linux USB one is not. Also the FreeBSD USB stack is dual-mode, both Host and Device? If you want we could arrange a time to talk a bit about a GSoc 2015 project involving USB and FreeBSD. The "mail@" is not valid, and should probably be "hselasky@" :-) --HPS
