    Prateek Bansal
    Hi Jeff, My understanding is you need to change it at the kernel build stage. Further, you will need USB OTG mode support to move between host and driver at run time that is not available on DM6467 EVM. Swami - please validate my understanding. Thanks, Prateek

    Our design with the L137/L138 using USB0 (the high speed connection) requires 5 hubs connected in serial fashion, that is one hub connected to a downstream hub connected to a downstream hub, etc. We tested this on a HP laptop, no problem.
