Tiva TM4C1294XL Board Ethernet AND USB

Has anyone seen an application or gotten one working with BOTH Ethernet and USB on the TIVA Launchpad TM4C1294XL?

Is there a CLEAN application that explicitly shows ALL of the settings necessary to enable the USB?

    I found the problem.  I missed the periodic call to USBOTGMain( )

    //
    // Tell the OTG state machine how much time has passed in
    // milliseconds since the last call.
    //
    USBOTGMain(GetTickms());

    I may write up the full procedure later.

    Hi Michael,

    I think I'm also facing same problem.

    I'm trying to use my USB pendrive as filesystem and serve pages over ethernet( with lwIP ).

    For me MSCCallback is never being triggered.

    I combined code from examples enet_io and usb_host_msc in tivaware for EK_1294XL. Could you please share with me how you solved the problem?
