My students wrote some code to use the USBCamera in RobotPy, but the USBCamera stuff is highly inefficient in python, if I recall correctly.
Here's a link to some of their code.
I've never tried sending it to the Driver Station... but I feel like I remember the students doing it, and it worked.
However, if you're just trying to *see* the feed, I would recommend using mjpg-streamer instead. Here's a CD thread about that:

And here's a
gist that contains scripts to make it work.
And if you want to read the images from mjpg-streamer using python and process it with OpenCV, the repo listed above has a bunch of code for that.
I'll be adding mjpg-streamer to the robotpy opkg feed for 2016, just haven't gotten around to it yet. Hopefully by the end of this week or week one.
