Hi Paul, > What can a user do about this? It looks like the I2C addresses need to be > added to `dell_lis3lv02d_devices[]` in `drivers/i2c/busses/i2c-i801.c`. Complain to Dell about the missing address ;) Until then: > [ 20.631866] i801_smbus 0000:00:1f.4: SPD Write Disable is set # cd /sys/bus/pci/drivers/i801_smbus/0000\:00\:1f.4 # ls -d i2c-? The last digit of the printout is the bus number. Then: # modprobe i2c-dev # i2cdetect <bus_number> And post the output here. If you are brave and see that the address 0x1d or 0x29 are printed in your output, you could try adding an entry to the array you already mentioned above with the address you found. It may be safer to do some sanity checking before, though. Happy hacking, Wolfram
