Hi Antonio,

it's most likely that the Airstar uses a different i2c adress. If you
have access to a windows box and a diassembler then you can take a look
at the driver codes to find out the adress. Another option would be to
try all configurations possible for the mt352 (shoudn't be more than 4,
I guess).

Good luck,

Niklas
