Trying to program TM4C123G on Ubuntu 14.04 gives LIBUSB_ERROR_ACCESS / Unable to find any ICDI devices

Other Parts Discussed in Thread: ENERGIA

1. The full message after the compile log:

Unable to open USB device: LIBUSB_ERROR_ACCESS
Unable to find any ICDI devices

2. Every time before I program I have to type in the console sudo usermod -a -G dialout [username] for the serial port to be visible to Energia. Is there a way to make it permanently visible?

I think you just have to add your user permanently to the dialout group - how this is done depends on your (Linux) distribution.

And, you might need to add an udev rule for your USB device (ICDI), allowing access for your/all users. The following link might serve as starter:

I did everything succesfully, as described in that article - got gid=100 - and I still get the same error.

Have you tried as root ?

What does lsusb say ?

What to have tried as root? Programming? Setting the privilegies? I did what was required under root and the rest as normal user.

Here's how lsusb sees the device: Bus 005 Device 002: ID 1cbe:00fd Luminary Micro Inc. In-Circuit Debug Interface
