Kernel Patch to Device Detected!

I get in touch with one of my contacts and he suggested me to try using tvtime, again.

scanning channel..
$ tvtime-scanner --norm=PAL
Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /home/bitto/.tvtime/tvtime.xml
Scanning using TV standard PAL.
/home/bitto/.tvtime/stationlist.xml: No existing PAL station list "Custom".

Your capture card driver: em28xx [Kaiomy TVnPC U2/usb-0000:00:12.2-5/258]
does not support studio-quality colour images required by tvtime.
This is a hardware limitation of some cards including many
low-quality webcams. Please select a different video device to use
with the command line option --device.

Message from the card was: Device or resource busy

Nothing's found.

Then only I know that the fimware has stop its support until kernel 2.6.28 while I'm using 2.6.31

$ uname -r
2.6.31-17-generic

So I have to install the kernel patch which add compatibility with backward kernel. Source

$ hg clone http://linuxtv.org/hg/v4l-dvb
destination directory: v4l-dvb
requesting all changes
adding changesets
adding manifests
adding file changes

This process took a long time that I decided to just download directly from the link.

Untar it.
$ tar xf v4l-dvb-bc2c81548b60.tar.bz2

$ cd v4l-dvb-bc2c81548b60/
$ make
