Re: KWorld VS-USB2800D recognized as PointNix Intra-Oral Camera - No Composite Input




Hi Mauricio,

Sorry for my late response. Yes, I was able to get it to work with the
current version of v4l.

I followed instructions given to my by Douglas Schilling:

shell> hg clone http://www.linuxtv.org/hg/v4l-dvb
shell> cd v4l-dvb
shell> make
shell> make unload
shell> make install 
shell> dmesg -c  (clear your dmesg)
shell> modprobe em28xx
