Workaround
A workaround for Arch Linux:
Add the I2C kernel module:
$ sudo modprobe i2c-dev
Check your I2C devices:
$ ls /dev/
You should find somthing like: i2c-0 i2c-1 i2c-2 …
Install the I2C tools:
$ sudo pacman -S i2c-tools
Find your device:
$ i2cdetect -l
The result could look like:
i2c-1 unknown i915 gmbus vga N/A
Now you can comunicate to your devices with these commands:
$ i2cset $ i2cdump
