There was a problem hiding this comment.
Maybe it is better to move the event_trigger initialization before the following attributes
input->enable(true);
set_frequency(frequency);
write_fs_arithmetic(_iio_device_path + "/buffer/length");

At enumeration stage Linux HID IIO async invocation may cause improper initialization order, resulting in Accelerometer's trigger driver mapping missing.
The patch establishes the required trigger mapping, thus allowing the accel_3d driver function properly
Addressing #2965.
