Could you try again with the current master of iio-sensor-proxy? Make
sure to install the file in the same location as in your distro
provided package.

I've added more debug/warnings to a few cases where it would have
silently failed in the past.

In particular, I don't see any messages that would be coming out of:
https://github.com/hadess/iio-sensor-proxy/blob/master/src/iio-buffer-utils.c#L512

Could it be that the sub-directory is populated after the device is
created in the kernel, causing a race?

Either that, or the contents of the scan_elements/ directory is not the
one expected by this code.

The output of this command should us that:
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
