system restart the device
Reboot or restart GUI?
Reboot.
It is not the first device with this problem. Whes system (linux) is restarted it loads drivers from the start, but this USB tuner needs power off before loading the drivers again.
That is a weird solution? Udev loading the drivers too early?
Yes... I think.
The similar problem I have with the DVBSky T330 USB tuner with Zgemma H9S and OpenPLi 8.0 (8.1). I had to implement similar procedure to get it working with Enigma.
