Change this to note that although it's fixed in p4, it is not yet fixed
in CVS.  Closing it early was my mistake.

 If possible, could you provide information about how to reproduce
 this problem, and a patch to fix it?

Symptom: You plug a USB device and it is not detected at all.

I am not using the old USB driver, but basically what you need to do is this:

ehci.c
==

void
ehci_pcd_enable(void *v_sc)
{
ehci_softc_t *sc = v_sc;

ehci_pcd_able(sc, 1);

+/* acknowledge any PCD interrupt */
+EOWRITE4(sc, EHCI_USBSTS, EHCI_STS_PCD);

+ehci_pcd(sc, sc-sc_intrxfer);
}

ohci.c
==

void
ohci_rhsc_enable(void *v_sc)
{
ohci_softc_t *sc = v_sc;
int s;

s = splhardusb();
ohci_rhsc_able(sc, 1);
splx(s);

+/* acknowledge any RHSC interrupt */
+OWRITE4(sc, OHCI_INTERRUPT_STATUS, OHCI_RHSC);

+ohci_rhsc(sc, sc-sc_intrxfer);
}
