That is correct. Sometimes the data received is 0300. But not as frequent as
you in your description. The first sample after power up, I can understand as I
have seen before. But here it is intermittent. There are no other events also
to see if there is some random mixup.

I want to see if this is lower than the logical min value, then we can return
as failed read.
If you go to /sys/kernel/debug/hid/
There will be folders. I think this sensor is under 0003:17EF:F006.000E.

if you read "rdesc" file, you may see something like this:

Physical(Sensors.LightAmbientLight) 
      Usage(1)
        Sensors.DataFieldIlluminance
      Logical Minimum(0)
      Logical Maximum(10000) 
      Unit Exponent(-3)
      Report Size(32)
      Report Count(1)
      Report Offset(208)
      Flags( Variable Absolute )

Check that.
