There are many ways to achieve your goal. The simplest one might be to compile 
the Linux HID layer into the webcamd deamon and have a compatible interface. 
This means no porting effort.

You will have to checkout and install the linux_make tool from the I4B SVN, 
referred to from the webcamd (/usr/ports/multimedia/webcamd) homepage:


And add some config entries to the config file for the HID layer, and possibly 
also resolve a few compile issues.
