Problems with TBS6618 driver

[Alb]

Hi everyone,

I'm having some kind of problem with my tv-card (tbs6618 dvb-c).
I have done all steps of installation driver (as it is written in the README_TBS6920_8920_UBUNTU) , but after reboot, when I write the command ( #dmesg | grep cx23885 ) I don't see any information, window of terminal is empty, also the folder (/dev/dvb) is missing and accordingly I can't recieve the signal at VLC player.

What the problem could be?
Thanks in advance.
