EK-TM4C123GXL: Board Will Not Show Up in Device Manager

Hello Joe,

Do you see the green LED on the LaunchPad?

And which of the two USB ports are you plugging into with the LaunchPad?

I have the usb plugged into the debug(the one next to the switch), the switch turned to debug, and the pwr led is glowing green while D1 is changing colors. 

Hello Joe,

Can you post a screenshot of Device Manager with expanded views for Ports (if displayed) and Universal Serial Bus controllers?

Also, has this board worked before? Do you have any other EK-TM4C123GXL LaunchPads that you can also test on the PC?

I reinstalled the drivers using a Windows 10 patch for everything except the two Stellaris ICDI entries as it would not work so I used the older drivers, both of which I found here http://software-dl.ti.com/tiva-c/SW-TM4C/latest/index_FDS.html and now Stellaris and Tiva both have entries but have warning labels and if I try to install the drivers directly from the device manager I get an error code. 

I had already installed those, to be safe I tried again and I keep getting this error: 

Hello Joe,

That is very strange... I've never seen that error reported before. Have you tried restarting the PC after the driver installation?

You may also want to completely uninstall the drivers, disconnect the board, restart your PC, and then try reconnecting and reinstalling.

I am not really sure what else to suggest as it looks like Windows is hung up about something with the driver and we haven't had any other customers run into this issue. 

Maybe you can track down where the driver is inside of the Windows system files and delete it that way to reinstall from scratch... though I've never tried to track that down and I imagine it would not be trivial.

On the windows 7, the board is listed as Base System Device and the pwr led is glowing what seems to be more yellow than green? Is that a hint towards something or should I chalk this board up as broken?

Hello Joe,

Usually Base System Device indicates a driver issue as well. Did you try and install the drivers on Win 7 PC too?

I would want to see another LaunchPad work before we assume it is a broken board, but if you can test with another LaunchPad and the issues do not come up, then yeah it probably is broken.
