Greetings,
I have the following device: Mygica T230 DVB-T/T2/C, although everywhere I see,
it is advertised as a good device, I'm unable to render it working.
I've tested on 4 different computers, in all the linux systems (gentoo with
kernel 4.13.3, rpi2 with kernel 4.9 and odroid with kerne 3.14 + media-build
drivers), I'm unable to get it to work properly. useally, it doesn't receives
anything and in the few times it does, the connection drops fast.
the fourth computer I've tried is a netbook running windows 10 and the device
works great.
e.g. I plug it into the rpi2, no reception, I move it to the gentoo machine,
the same, I then move it to the win10, it works.
I'm using the fw from the linuxtv.org website, scan dobe by w_scan shows this:

Thanks, Dagg.
