Hi.
I just purchased a new DVB-T2 USB dongle on Ebay[1].
This dongle reports itself as Astrometa DVB-T2, but it does not work
with the current v4l-dvb kernel (tested with 2942273).
After a teardown[2], I realized, that it has a different (and unknown,
as the manufacturer removed the label) tuner chip, MN88473 and RTL8232P.
w-scan is able to find some multiplexes, but it is not able to tune and
decode, so the tuner seems to be at least partially supported ("Info: no
data from PAT after 2 seconds", see the log in [3]).
MN88473 is not detected, and firmware is not loaded (even if the
previous supported version contains the same chip).
The bundled CD contains Windows drivers.[3]
Could anybody provide me a hint, how to debug it or make it working?
