How to add an I2C/SMbus device module?

kgregory · 2013-04-23 16:27:49

I'm trying to write software that accesses a specific I2C device on the SMBus. I installed the i2c-tools and lm_sensors packages and when I use sensors-detect, it briefly adds the I2C/SMbus from my chipset as /dev/i2c-0, but then drops it when it finishes. How can I permanently add the bus as /dev/i2c-0 (or similar) so that I can access it with the i2c-tools library?

It says which driver it uses. You can load this driver manually later.

How do I do that? Perhaps I should be in the newbie forum :-(

Like every other kernel module, i.e.

modprobe whatever

where whatever is name of the driver that sensors-detect says you need, e.g. it would be i2c-piix4 on my system.
