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 al= so to see if there is some random mixup. I want to see if this is lower than the logical min value, then we can retu= rn 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)=20 Usage(1) Sensors.DataFieldIlluminance Logical Minimum(0) Logical Maximum(10000)=20 Unit Exponent(-3) Report Size(32) Report Count(1) Report Offset(208) Flags( Variable Absolute ) Check that. --=20 You may reply to this email to add a comment.
