Pls add in-place description for what is doing on for maintainers.
One more thing - currently it will run for both Accel and Gyro, but we know that the issue occurs with Accel.
so even if accelerometer will be fixed immediately we'll still wait for 200 msec for gyro ( that won't start)
Can the condition "KERNEL=="iio*", ATTRS{idVendor}=="8086" be further fine-tuned?

Where is this set to true? I though it is a command line flag

The code segment need to be refactored into the udev-rules so it will be also picked up when the udev-rules are installed not by this script, such as in case with Debian or manual install
--uninstall : remove permissions for realsense devices. --auto_power_off : add script for automatic power off. Remove auto power off from config/99-realsense-libusb.rules
…t to 0. No hard code sleeping time. remove power-down line from config/99-realsense-libusb.rules scripts/setup_udev_rules.sh sets the power-down line to 99-realsense-libusb.rules file.
…sense-libusb.rules increase timeout to 200mSec based on a NUC test. Modify rule to apply for accel sensor only.

Test check if power is down for a newly connected device and after resetting it. It also check that while the first camera is running, connecting a second camera wont interfere. A flag '--help' prints a usage message.
Add timeout of 10 seconds for device to be connected.

On kernel 5.x.x.x there is an issue with iio sensors - some of them does not reduce power consumption after connection.
This udev-rules correction disables the sensor after it's initial connection.
