bug: i2c-INVN6500:00: unexpected HID descriptor bcdVersion (0xca9b)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Looking back through boot logs this message is seen on all kernels used
on this Asus T300CHI, from v4.15 onwards:

hidraw: raw HID events driver (C) Jiri Kosina
i2c_hid i2c-INVN6500:00: i2c-INVN6500:00 supply vdd not found, using

i2c_hid i2c-INVN6500:00: unexpected HID descriptor bcdVersion (0xca9b)

inv-mpu6050-i2c i2c-INVN6500:00: i2c-INVN6500:00 supply vddio not found,
using dummy regulator

It's not clear if this is a warning that can be disregarded or an
indication the protocol isn't being completely decoded.

The accelerometer is working correctly but the ambient light sensor
isn't. I tested that by shining an LED camera light around the edges of
the device where the sensors are located and monitoring for changes.

I'm reasonably sure the light-sensor has worked previously but it isn't
something I would generally notice since the device is used in fairly
constant low-light conditions.

This may or may not be related to the error message.
