What do you see when you look in /sys/bus/spi/devices? You should see a directory for your device. What do you see in /sys/bus/spi/drivers? In here you should see your driver. If they are both there, then you just have a problem matching your driver name to the device name. g. -- Grant Likely, B.Sc., P.Eng.
