You'll probably get a better response by asking on the freebsd-usb mailing
list.
The following debug nodes for USB in 8.0 are present:
sysctl hw.usb | grep debug
hw.usb.ehci.debug: 0
hw.usb.ohci.debug: 0
hw.usb.uhci.debug: 0
hw.usb.ctrl.debug: 0
hw.usb.umass.debug: 0
hw.usb.debug: 0
hw.usb.dev.debug: 0
hw.usb.ugen.debug: 0
hw.usb.uhub.debug: 0
hw.usb.proc.debug: 0
hw.usb.ulpt.debug: 0
hw.usb.ucom.debug: 0
hw.usb.uhid.debug: 0
hw.usb.ukbd.debug: 0
hw.usb.ums.debug: 0
Your first step should probably be to get a verbose boot log (boot -v) - one
of the USB developers will likely know better than I do which sysctl debug
nodes to set to get more details.
Aloha,
If the node is disappearing for the USB device and it is connected by a
cable to the box try replace the cable. We had one here that would not
stay listed on the hardware and it was the cable connector gone bad.
I have never had a USB device lock up the box though.
