Dear Wolfram,


Thank you again for the prompt reply.

It does. After your command, Linux logs:

```
[ 2110.787000] i2c i2c-6: new_device: Instantiated device lis3lv02d at 0x29
[ 2110.791932] lis3lv02d_i2c 6-0029: supply Vdd not found, using dummy 
regulator
[ 2110.791981] lis3lv02d_i2c 6-0029: supply Vdd_IO not found, using 
dummy regulator
[ 2110.809233] lis3lv02d: 8 bits 3DC sensor found
[ 2110.900668] input: ST LIS3LV02DL Accelerometer as 
/devices/platform/lis3lv02d/input/input23
```

I can cook up a patch, if you want.


Kind regards,

Paul
