How to perform scan for isdb-t service

Hy guys , I recently bough a tbs6814 card.
I installed on my centos 7 server and installed drivers following tbs docs.
I can confirm drivers are ok doing:
Code: Select All Code
[root@tvheadend ~]# lspci -v | grep -E "TBS|Kernel"
4:00.0 Multimedia controller: TBS Technologies DVB Tuner PCIe Card

Problem is that , using w_scan util , can not perform scan.
Here is the output:

Code: Select All Code
[root@tvheadend ~]# systemctl stop tvheadend
[root@tvheadend ~]# w_scan -ft -c AR
w_scan -ft -c AR
w_scan version 20140727 (compiled for DVB API 5.10)

main:3886: FATAL: ***** NO USEABLE TERRESTRIAL CARD FOUND. *****
Please check wether dvb driver is loaded and
verify that no dvb application (i.e. vdr) is running.


Any ideas ?
How can I detect signal strengh and perform scan ?
Regards,
leostereo
