Re: Error:Could not open file `/dev/i2c-1': No such file or

Ah!, I forget it, This is what someone said in another forum: "I've spent a lot time in the module loading maze.

Re: Error:Could not open file `/dev/i2c-1': No such file or

Thank Joan but,
Yes I have already done that and I still have the same problem (Error:Could not open file `/dev/i2c-1': No such file or directory)

After running lsmod|grep i2c, I have:
i2c_dev 6027 0
i2c_bcm2708 4990 0

Thanks a lot anyway,
Any idea apart from that?

How many i2c buses can I use with new RaspberryPi 2 B model?

I am not sure if the second i2C bus (pin 27 BCM0: ID_SD and pin 28 BCM1: ID_SC) is only for use with i2c EEPROM for configuration purposes.
Thank you.
