Looks like you may be out of luck.
Supported Operating Systems :
>> Kensington VideoCAMs are only supported under
Windows 98 and Me. They are not supported under
Windows 95, NT, 2000, or XP.
>> Due to a changing market, Kensington has made a very difficult business decision. As of 2001, Kensington exited the Imaging business in order to focus on other products.
>> As a result of this, Kensington no longer develops drivers for the #67014 Kensington VideoCAM, #67015 Kensington VideoCAM VGA, or the #67016 Kensington VideoCAM Super VGA. Thus, VideoCAM drivers for Windows XP or 2000 operating systems have never been developed, nor will be supported by Kensington.
