Re: IR device at I2C address 0x7a

[Daro <ghost-rider@aster.pl>]

Hi Jean,

Thank you for your answer.
It is not the error message itself that bothers me but the fact that IR 
remote control device is not detected and I cannot use it (I checked it 
on Windows and it's working). After finding this thread I thought it 
could have had something to do with this error mesage.
Is there something that can be done to get my IR remote control working?
Thanks for your help in advance.

Best regards
Darek
