Yes, please.

These i2c errors are "correct". The *Star Cards/Boxes don't have any 
information stored, which determines the actual type. So we have to probe 
for the right demodulator to find it out. So just ignore the i2c-errors on 
the driver load.

The number of ack-errors will be lower in a future commit of mine. But one 
ack-error per probe-i2c-read, will stay.

Did you run azap with the -r parameter?

Maybe you want to update your udev-scripts?
