Linux Headers Needed to Compile New Drivers

I am working on a special project - details will be shared if we are successful - and for the project need to install some drivers that are missing from the Firewalla Purple.

We need to install the Linux headers but have not been able to install them so we can compile the driver sources.  Better yet, if you already had the drivers we need (uvcvideo.ko and usb_f_uvc.ko) you might save us a LOT of work.

Suggestions?
