EK-TM4C123GXL: Connect Tiva in device mode to windows10 PC

Part Number: EK-TM4C123GXL

Hello, 

I need to connect the Tiva board to a windows 10 PC in device mode (connection through USB to the left side of the board, and switch on the left) 

I would like to see the port appear in the list of peripheral but I can't see anything in device mode.

However, when I am connected in debug mode I can see the port ... 

I tried to install the LM_FTDI driver from here : www.ti.com/.../LM_FTDI_DRIVER, but I can't understand how to do it properly.

Do you have any solution ? 

Thank you for your help !

    First, I assume you power the EK-TM4C123GXL by moving the power select switch to the "Device" mode when connecting to the "Device" USB connector.

    Is there any program in the flash of the device? If the flash is erased, specifically if locations 0x0000 and 0x0004 are all 0xFFFFFFFF, then the device will run the ROM bootloader which will setup the USB port as "Stellaris Device Firmware Upgrade".

    If there is code programmed into the part, it is the responsibility of that code to setup the USB.
