That question made me go back to the man page and dig through the sources again.  It's the default/most recent configuration from yesterday's live CD.

	cpu% cat usbdb
	# only kb,  disk, and ether  are prepared for embedding.
	# others are not yet converted to sit in the usbd device driver library
	embed
		kb	csp=0x010103 csp=0x020103	args=
		disk	class=storage			args=
		ether	class=255 csp=0x00ffff		args=
		serial	class=255 csp=0xffffff vid=0x9e88 did=0x9e8f	args=
	#	wifi	class=0 csp=0 vid=0x0bda did=0x8192	args=
	#	wifi	class=0 csp=0 vid=0x148f did=0x2870	args=


Another side note: I had to explicitly do the following for anything to show up:

	cat% mount /srv/usb /n/usb
