Hi Antti, Thanks for the review. I agree that the I2C xfer does not look too elegant at the moment. Maybe it could be worth investigating if same methods could be used for all these devices. Alternatively I could have created another function for I2C xfer using the I2C_GENERIC_RD and WR commands, but then again the differences were so small... Would you suggest to move the non-endpoint related registers somewhere else from the init function? I just reused that as it was convenient... Tuner attach?
