From: Oliver Schinagl <oliver@xxxxxxxxxxx>
This is initial support for the Asus MyCinema U3100Mini Plus. The driver
in its current form gets detected and loads properly. It uses the
af9035 USB Bridge chip, with an af9033 demodulator. The tuner used is
the FCI FC2580.
I have only done a quick dvb scan, but it failed to tune to anything.
Using dvbv5-scan -I CHANNEL <channelfile> It did show 'signal 100%' but
failed to tune to anything, so I don't think signal strength works at
all. Since I have really bad reception where my dev PC is, I may simple
not receive anything here.
