I've done that: root@aaa:~# lsmod | grep i2c i2c_dev 3382 0 i2c_core 12703 1 i2c_dev But, nothing of interest in dmesg other than: [108414.944722] i2c /dev entries driver and running i2cdetect still turns up nothing: root@aaa:~# i2cdetect -l Any thoughts? Does this specific Winbond chip require a device specific kernel module to operate such as those found in /lib/modules/2.6.32-5-486/kernel/drivers/i2c/busses ?
