Issue Description

Timestamp: 1573383002959.180176
Severity: Warn
Description: RealSense UDEV-Rules are missing!
UDEV-Rules permissions configuration
for RealSense devices.

Missing/outdated UDEV-Rules will cause 'Permissions Denied' errors
unless the application is running under 'sudo' (not recommended)
In case of Debians use:
sudo apt-get upgrade/install librealsense2-udev-rules
To manually install UDEV-Rules in terminal run:
$ sudo cp ~/.99-realsense-libusb.rules /etc/udev/rules.d/99-realsense-libusb.rules && sudo udevadm control --reload-rules && udevadm trigger

I have run this commands but it doesn't work.

I have the similar issue when installing librealsense from source.
The rs-multicam only detects D435 camera. SR300 is not detected by the software
Operating System & Version : Ubuntu 18.04.3

Yes,I'm install by source code.
And how can I fix this problem.

@lxz1104 , please be aware that this is a known issue for SR300 with V2.30. Please revert to the previous v2.29.
