Hello community!
I'm using the EK-TM4C129XL eval board, trying to run the USB-dev-cserial example code. I'm able to load the code through the debug port without any trouble, and under the Device Manager, I can see the "Stellaris Virtual Serial Port" for the debug port. When I plug in the device USB port, however, I see the install window attempting to install the "Virtual COM Port." When it appears to have finished and I look in Device Manager, I don't see a new COM port. Instead, under "Universal Serial Bus controllers," I see a new "USB Composite Device" with the yellow warning symbol in the lower right corner.
I've tried installing the various .inf drivers under the "windows_drivers" folder, but it doesn't seem to help. I do get different results when I try to install using different versions of TivaWare_C_Series:
Version 2.1.0.12573 appears to install the drivers without any problems.
Version 2.1.1.71 fails to install with the message, "A problem was encountered while attempting to add the driver to the store."
Version 2.1.3.156 fails to install with the message, "The has for the file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering."
I'm hoping someone has an idea as to why I'm not getting the virtual COM port when I plug in to the device port on my eval board. I'm running Windows 8.1, with CCS 7.1.
Thanks for your time.
