[A. Andria]

Hi,

I have change the mobile phone to nokia 6510 with IrDA support.
The usb known as Mobile Action Technology, Inc. MA-620 Infrared Adapter

root at asep-ubuntu:~# /usr/bin/lsusb
Bus 002 Device 002: ID 0df7:0620 Mobile Action Technology, Inc. MA-620 
Infrared Adapter
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

 From the dmesg i found this :

The question is :
1. How to enable IrDA connection on Linux ?
2. How to make sure that the IrDA work correctly ?

Any help would be appreciated.
