Here is a post about new USB WebCam support you
may be interested in.

-------
From: "Peter S. Housel" <housel@acm.org>

I have written for FreeBSD (and probably NetBSD) a simple-minded image
capture program for USB webcams based on the OmniVision Technologies
OV511 bridge chip attached to an OV7610 CCD imager.  This includes
inexpensive webcams such as:

This is a simple image capture program for USB webcams based on the
OmniVision Technologies OV511 bridge chip attached to an OV7610 CCD
imager.  This includes webcams such as:

 * Creative Labs WebCam 3
 * D-Link DSB-C300
 * Puretek PT-6007
 * Koala-Cam
 * Lifeview RoboCam
 * AverMedia InterCam Elite
 * MediaForte MV300

The program is heavily based on the OV511 linux driver by Mark
W. McClelland.  (See http://alpha.dyndns.org/ov511/ for more
information).  Recent versions of that driver support a wider array of
cameras; if it supports something that this program doesn't then
contact me and I'll see what I can do.

You can download version 1.0 of the program at:

Since USB webcams transfer image data using an isochronous endpoint,
support for isochronous transfers in the FreeBSD/NetBSD generic USB
device (ugen) driver is required.  A patch adding this support is
also available on my home page:

The patch has only been tested under FreeBSD 5.0-CURRENT.
