Device Connection Issue

If your device is not shown in list that pop-up while connection establishing step then your device might be not connected properly to port or their might be the browser compatability issue. Please ensure that it is properly connected to the port. Reseating connection cable might also helps to resolve this issue. If your device is connected to any other application, please disconnect it and try again.

Serial Data Transmission Permission Issue

For linux users, the currently logged in user should have read and write access the serial port over USB. On most Linux distributions, this is done by adding the user to dialout group with the following command:

usermod -a -G dialout $USER

on Arch Linux this is done by adding the user to uucp group with the following command:

sudo usermod -a -G uucp $USER

Make sure you re-login to enable read and write permissions for the serial port.
