    Myself/others are uncertain as to your meaning of,  "Usb Controller."

    Should you be seeking solid guidance - regarding your MCU's  USB capabilities - I list the following:

    • SW-TM4C_BOOTLDR-UG-2.1.4    This is a 76 page vendor document - as the title well notes - describing the MCU's operation under bootloader.

    • W/in that document appears, 

    "The Texas Instruments® Tiva® boot loader is a small piece of code that can be programmed at the beginning of flash to act as an application loader as well as an update mechanism for applications running on a Tiva ARM® Cortex™-M4-based microcontroller.  The boot loader can be built to use either the UART, SSI, I2C, CAN, Ethernet, or USB ports to update the code on the microcontroller."

    And, "for USB DFU, updates are performed via the standard Device Firmware Upgrade (DFU) class."

    Should your intent be to, "Update firmware w/in your MCU - via USB - then the data presented here - strongly suggest that such IS POSSIBLE!      Just as you requested!
