usb broken in BETA5

Hi,

Somewhere between betas 3 and 5, my usb broke.  The actual controllers 
and hubs are found on boot...

usb0: <Intel 82801DB (ICH4) USB controller USB-A> on uhci0
usb0: USB revision 1.0
uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
uhci1: <Intel 82801DB (ICH4) USB controller USB-B> port 0x1820-0x183f 
irq 19 at
device 29.1 on pci0
uhci1: [GIANT-LOCKED]
usb1: <Intel 82801DB (ICH4) USB controller USB-B> on uhci1
usb1: USB revision 1.0
uhub1: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub1: 2 ports with 2 removable, self powered
uhci2: <Intel 82801DB (ICH4) USB controller USB-C> port 0x1840-0x185f 
irq 18 at
device 29.2 on pci0
uhci2: [GIANT-LOCKED]
usb2: <Intel 82801DB (ICH4) USB controller USB-C> on uhci2
usb2: USB revision 1.0
uhub2: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub2: 2 ports with 2 removable, self powered

However, plugging in a USB device does nothing.  I've tried multiple 
devices which work on other machines, in all of the ports on the 
computer.  It works when I boot this machine into linux.  it doesn't 
work with usbd on or off.  Can anyone help me?

thanks,
brian
