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. -- Bruce Cran
