Henry,

Thanks for your response.

Well, I already found that this chip isn't supported yet. Basically, what I'm
into is getting it or any other driver compatible with Linux 3.0 and
Android 2.3 to work with our hardware. The problem is that the newest
firmware-driver pair I can get for this chip is 4.217.95.x and it would require
pretty much work to make it compatible with our software target, because
the driver was designed for Linux 2.6.32 sources specific for this hardware
with much hardcoding done.

I'm already in contact with Franky Lin <frankyl@broadcom.com> about our issue,
should I also discuss this topic with Howard?

Best regard,
Tom
