Hello. I'm trying to get monitoring working for Asus Fan Extension Card. The card has NCT7802Y on it. "modprobe nct7802" doesn't fail, the module loads, no errors in dmesg, but hwmon device doesn't show up too. What am I missing? The motherboard is Asus Prime X299-A, with NCT6796D on it (mostly working).
modprobe doesn't guarantee that the device is instantiated due to chip limitations (its device ID register is not always accessible). We also don't know if the chip is directly connected to an i2c bus visible to the CPU, or to an embedded controller. You could try to run i2cdetect to see if the chip is visible. If it is, you may have to instantiate it manually. If it isn't, the chip is not visible to the CPU, and you are out of luck. What is wrong with the NCT6796D ? Thanks, Guenter
