Description Matthieu Pepin 2020-02-28 16:28:38 UTC 
I bought a Chuwi Hi10 X Gemini Lake tablet. It comes with a MXC6655 MEMSIC Accelerometer (according to the device manager in Windows 10, I'm not too sure how to dump I2C information in Linux). The device is not detected by the kernel, thus auto-rotation does not work.

Please add support for this accelerometer. I can provide debug output if you need any info about the sensor.

dmidecode output:
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.2.0 present.

Support have been added already [1]. It is fully compatible with MXC4005.

How did you get it working?  The MXC6655 accelerometer is not working with MXC4005 driver for me on my Chuwi tablets (UBook X 2023 and UBook X Pro 2023). 

I've submitted a new bug report: https://bugzilla.kernel.org/show_bug.cgi?id=218578
