In the file "/sys/dev/usb/ohci.c" change the function "ohci_rhsc_enable" so
that it looks like shown below. Make sure that you get everything right.
void
ohci_rhsc_enable(void *v_sc)
{
ohci_softc_t *sc = v_sc;
int s;
s = splhardusb(); /* XXX has no effect on FreeBSD */
ohci_rhsc_able(sc, 1);
/* acknowledge any RHSC interrupt */
OWRITE4(sc, OHCI_INTERRUPT_STATUS, OHCI_RHSC);
ohci_rhsc(sc, sc->sc_intrxfer);
splx(s);
return;
}
If you are loading the USB module,
simply cd /sys/modules/usb; make clean all install clean
Else recompile the kernel.
Then reboot.
Does it change anything ?
