    TM4C123x has a silicon bug, which causes trouble on communication with low-speed devices over a hub, described at USB#01 in TM4C123x Silicon Errata.

    But communication with full-speed device over a hub should work. Try it ;-)

    TivaWare libraries give "universal" binary over differences of MCU hardwares, using "CLASS_IS_TM4C123" and "CLASS_IS_TM4C129" macros (hw_types.h). Unless your source would directly access to the features (registers) specific to TM4C129X, your code binary could work on TM4C123X. But usually, you'll need to tune your source code for the differences of board components, such as crystal., pin connections.

    USB keyboards are usually low-speed.
