Probably. We forked and made a few changes to the uvc_cam driver to support
camera_info_manager and some dynamic_reconfigure because we wanted a uvc
based driver. I'm not sure what the pluses and minuses are for however
usb_cam interfaces with the camera vs. using UVC like uvc_cam does. Any have
some experience or thoughts on that?

See https://github.com/ericperko/uvc_cam for the uvc_cam fork.
