Hi Sril,
the only af9035 driver currently under active development is the one
from Hans-Frieder Vogt (af903x).

The patch in attachment is a quick port of the support for the tda18218
tuner (and hence the a835/b835 dongles) from the old drivers that are
floating around (all derived from the xgazza patch).

The problem with the xgazza patch is that it uses the tuner
initialization script and the firmware of another stick (with a
different tuner, the TUA 9001) so it is not working optimally. I have a
07ca:b835 and it works surprisingly well on my systems, but there are
many users (like you) who report I2C errors.

We need to extract a proper firmware and/or initialization script for
the tda18218 from the Windows driver to solve this problems.

There is also a small patch for the tda18218 that is needed to tune VHF
frequencies (with 7MHz bandwidth).

Best regards,
Gianluca
