I disabled devd, but I dont have anything else like hald or webcamd
running. I also disconnected all usb devices. I powered off the unit,
disconnected, then reconnected it to the box and started usbdump. I
didnt see the above sequence. I started apcupsd and it seems to be the
one sending that sequence to it.

I can try. I dont have any contacts there, but I will bcc' one of the
developers of apcupsd to see what he thinks. I attached the output of
truss and the usbdump to see if that sheds any light on the issue and
why FreeBSD is crashing the device and not Linux.
