(In reply to Hans Petter Selasky from comment #1)
Thanks for the prompt reply.
I don't see any evidence of it in webcam(d). I
grepped the entire tree against '75bf' which only
returned results from broadcom wireless and an m68k
source.
I'm a bit stuck for what to search against; aside from
'06cb' || 'synaptics' which turn up plenty.
FWIW usbconfig returns this on my FreeBSD box

are there any clues here that may help in further investigation?
Thanks again. I'll keep looking...
