Hi,

I have bought this adapter and on ubuntu 20.4 give me error scan no data, but on libreelec works fine.

I have put the firmware on /lib/firmware/dvb-demod-mn88473-01.fw and i have do media_build (it's necessarily build media?)

After many experience i don't succesfully put work on this dvb-c works on ubuntu

I have view the log on connect usb:
