em28xx?

[Andrew Gallatin]

Hi,

I was pointed to the webcamd / cuse4bsd project as a way to run a DVB
based device on FreeBSD.  I have a Kworld UB435Q (em28xx, lgdt3305
demod):

% sudo usbconfig -d 4.2
ugen4.2: <USB 2870 Device vendor 0x1b80> at usbus4, cfg=0 md=HOST
spd=HIGH (480Mbps) pwr=ON

Unfortunately, this does not seem to be supported by the webcamd
project, as the em28xx driver is not compiled in.   When I naively try
to compile it by uncommenting the 'SRC+= em28xx-*c' lines in webcamd's
Makefile, the build fails spectacularly
(see appended output).  Has anybody tried  this before?  What are the
general steps for porting a driver?

Thanks,

Drew
