Hi Aapo,

Thanks for your email.

Assuming for a moment that I were to write a driver for the TUA6045:

1. Is it at all likely that an existing driver could be adapted to
work with this device? i.e. are other tuners by Infineon supported
under Linux and, if so, how significantly do the tuners typically
differ in terms of how drivers interact with them? It would, after
all, be much easier to start with something (i.e. an existing driver)
than to start from scratch.

2. If I did succeed in writing such a driver, would I still face an
issue with firmware? i.e. the stick seems to be loaded (under Windows
XP) with C&E firmware rather than the Hanftek firmware that Linux
loads onto it. Is there any way to get hold of this (C&E) firmware or
to extract it from the Windows drivers?

Best wishes,

Luc
