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
