Hans, This wild guess do NOT works. I binary sect xhci.c in SVN, found that *r245732 *<http://svnweb.freebsd.org/base?view=revision&revision=245732>* introduce the bug.* <http://svnweb.freebsd.org/base?view=revision&revision=245732> revert to r345731 fixed this USB problem in 9.2R I also copy xhci_interrupt(struct xhci_softc *sc) from 9.1R to CURRENT, CURRENT also works!
