Maybe this is helpful, this is what happen when I force my Network to Scan.

    hmm maybe antenna (reception is too worse)? maybe the stick is faulty ?

    unlikely that all drivers fail :) (not ruled out of course)

    I've an online store and I ordered 10 of this devices, all of them do the same. They can be broken but is very strange.

    Yes I can view all channels available on the two muxes in my location..

    Did you create the correct network for your location and apply it to the device in the tuner settings in tvheadend?

    Yes, I did all the steps so many times and with differents tests. Even my customers tried to configurate them with same results.

    I just plugged in my rtl2832 to a running LibreElec and was able to set it up in Tvheadend without problems.

    Did you see any channel?

    Cvh, in my case I saw the adapter but it fails in the scan moment.

    Thanks!

    I think there is not a correct driver for this device.

    I just investigate a lot for this subject and I finally arrive here because the comment of an user in this post:

    DVB-T USB RTL2838

    The problem Is that the device is detected by LibreELEC and TVheadend but it doesn't work propertly with the muxes.

    Thanks a lot and regards. If you need any more info please ask me.
