Here you go: root@gladys:~# ls /sys/devices/pci0000:00/0000:00:13.0/{33AECD58-B679-4E54-9BD9-A04D34F0C226}/001E:8086:22D8.0001/HID-SENSOR-200073.8.auto/iio:device1/scan_elements in_accel_x_en in_accel_y_en in_accel_z_en in_accel_x_index in_accel_y_index in_accel_z_index in_accel_x_type in_accel_y_type in_accel_z_type > If it doesn't warn on startup, and it fails to work, then we're > probably looking at a bug in the kernel... Here is the output. The latest master still doesn't work. However, it has the same behaviour that running the broken version of iio-sensors-proxy (207b5bbd8) will cause the good one start working (92fa6ea9e). -- Logs begin at Tue 2016-06-14 22:19:47 BST, end at Tue 2016-06-14 22:20:52 BST. -- Jun 14 22:19:48 gladys systemd[1]: Starting IIO Sensor Proxy service...
