Dropping stable This patch is a follow-up to the one below. The USB ID is different for the Lenovo Yoga 2 13. What Guilhem sent you was verified against Yoga 2 11 and Yoga 3 14. I guess this product line comes with a couple of variants. Without the quirk, no data is received from the accelerometer. I have verified the patch, testing this on 4.3-rc4 (and 4.2 stable). With this patch, proper orientation data is received. rrs@learner:~/Community/UpstreamSources/linux-upstream_GIT (stable-42)$ monitor-sensor ** Message: Accelerometer orientation changed: bottom-up ** Message: Light changed: 0.000000 (lux) ±** Message: Accelerometer orientation changed: left-up ** Message: Accelerometer orientation changed: bottom-up ** Message: Accelerometer orientation changed: left-up ** Message: Accelerometer orientation changed: normal ** Message: Light changed: 29.999999 (lux) monitor-sensor can be found in the iio-sensor-proxy tool. commit 47eeca8a4838714e582c2a3058458408a328ed60 Author: Guilhem Lettron Date:   Sat Jun 27 17:02:23 2015 +0200     HID: sensor-hub: Add in quirk for Lenovo Yogas with ITE          Like yogas with TEXAS_INSTRUMENTS, yogas with ITE chips needs     to be initialized with enumeration quirks.          Signed-off-by: Jiri Kosina -- Ritesh Raj Sarraf | http://people.debian.org/~rrs Debian - The Universal Operating System
