Configuring UDEV system on Linux Systems for CyberAtom Devices

Depending on your Linux setup it might necessary to give proper permissions to be able to access CyberAtom as USB devices using regular user privileges. The following procedure has been tested on Ubuntu 14.04 LTS and should be straightforward to apply on Debian or similar distributions.

Create user group `cyberatom`.
```
$ sudo groupadd cyberatom
			
```

Add the user account to this group.

$ usermod -a -G cyberatom <username>

You need to re-login to have user account reflected in the user account settings. This can be checked by:
```
$ groups
			
```

Within `/etc/udev/rules.d/` create rule file named `50-CyberAtom.rules` with content:

SUBSYSTEM=="usb", ATTRS{idVendor}=="ffff", ATTRS{idProduct}=="0002", GROUP="cyberatom", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", GROUP="cyberatom", MODE="0666"

Restart udev system with:

sudo restart udev

sudo udevadm control --reload

Re-connect your CyberAtom device to the USB port of your PC machine.

You should be able to see the details of your CyberAtom device without any restrictions. E.g. the following command:

$ lsusb -d ffff:0002 -v

should give similar output:
