 	/dev/uscanner0 was not being created in my installation.  This
was the source of my grief.  That said the kernel somewhat saw it:

Sep  8 13:25:41 burp kernel: device_attach: uscanner0 attach
returned 6
Sep  8 13:26:27 burp kernel: ugen0: at uhub0 port 3 (addr 3)
disconnected
Sep  8 13:26:27 burp kernel: ugen0: detached
Sep  8 13:26:33 burp kernel: uscanner0: at uhub0 port 2 (addr 2)
disconnected
Sep  8 13:26:38 burp root: Unknown USB device: vendor 0x05d8 product
0x4002 bus uhub0
Sep  8 13:26:38 burp kernel: uscanner0: <vendor 0x05d8 product 0x4002,
class 255/255, rev 1.10/1.00, addr 2> on uhub0
Sep  8 13:26:38 burp kernel: uscanner0: bulk-in and/or bulk-out endpoint
not found

 	From the documentation there appear to be conflicts in vendor
and device ids and if you check these against usbdevs, usbdevs will see
this device and vendor as something quite different from what they are.
That said the kernel is not using usbdevs at this point.  The man page
sane-usb explains the workaround for this.

 	What Freebsd are you using Warren?

 	Cheers.
