Arduino Firmware Upload Errors

Introduction

Upload of firmware works differently on different computers. On Dell Precision M6500 - upload to the Arduino does not work. In this case, the port shows as /dev/ttyUSB0.

On another board where upload works, port name includes (Arduino Mega 2560)

The funny thing is that on another computer, both of these boards work. The difference is the operating system. It worked with OSE Linux live USB. So I used the OSE Linux Live USB on the computer where the firmware upload didn't work, and problem was fixed.

This appears to be a simple permission error.
