Issue Description

I get the above warning after launching realsense viewer, with no devices connected

This warning points out to missing steps during the installation process - in particular:

3. Run Intel Realsense permissions script located from librealsense root directory:
   ./scripts/setup_udev_rules.sh

Alternatively, you could remove the manual install via sudo make uninstall and install everything via apt.

I get the same error message. After trying to install it with through apt-get the same error occurs.

After uninstalling and reinstalling through the package manager the error is still occurring. That's why I tried to copy the missing rule (https://raw.githubusercontent.com/IntelRealSense/librealsense/master/config/99-realsense-libusb.rules) manually to the directory /etc/udev/rules.d/99-realsense-libusb.rules. I get a new error now.

@dorodni I appreciate that, however running ./scripts/setup_udev_rules.sh causes the error message illustrated by @sodom89 last screenshot - "Multiple udev rules found"

Deleting one manually, leaves me with the error message I created the issue with.

Unfortunately, this procedure does not solve the problem. I also reinstalled the system with Ubuntu 18.04 LTS and installed it via the package manager with apt. Unfortunately the error remains.

I was able to solve the issue by installing librealsense the manual way.
