Tvheadend

Spent one week on this, tried everything I can find online and still no working, please please please help!!!

First I am trying to use tvheadend on my ubuntu 14.04 server. I followed Complete Setup Guide for TVHeadEnd, Ubuntu, HDHomeRun Tuner, XBMC, and North American Program Guides and it doesn't work. The guide is for ubuntu 10.04 - 12.04, so I compiled the dvbhdhomerun by myself. No services found. I tried everything I can and I realized the problem is dvbhdhomerun. Below is all the info. Please help.

Server:

~$ lsb_release -a

hdhomerun info:

By using hdhomerun_config scan, I got all channels I suppose to get.

Obviously tvheadend got no service is normal since w_scan and scan couldn't get any channel neither. I think the problem is causing by dvbhdhomerun driver. Is it anything else I can provide to help solving my problem?

Thanks a lot in advance.
