I'd ask this question in the Persian ubuntu forum but unfortunately I have not received any answer.

    The top of your lsusboutput is missing (especially the ID), and you did not tell about your Ubuntu/kernel version, so it is difficult to answer. Please have a look at linuxtv.org/wiki/index.php/DVB-T_USB_Devices/Full to find if it is supposed to work (ID and kernel version provided). – ridgy Mar 26 '17 at 13:47

    Can you indicate which kernel you are using? Have you tried the method set out here – Nick Sillito Mar 26 '17 at 13:47
