//*****************************************************************************

//! This structure is passed to the USB library on a call to USBDCDInit and

//! various USB event handlers and pointers to each of the standard device
//! descriptors.

    //!   [1]   - String 1 for the first language listed in descriptor 0.

    //!
    //!   ...
    //!
    //!   [n]   - String n for the first language listed in descriptor 0.
