// Global Constants
//-----------------------------------------------------------------------------

// All descriptors are contained in the global structure <gDescriptorMap>.
// This structure contains BYTE arrays for the standard device descriptor
// and all configurations. The lengths of the configuration arrays are
// defined by the number of interface and endpoint descriptors required
// for the particular configuration (these constants are named
// CFG1_IF_DSC and CFG1_EP_DSC for configuration1).
//
// The entire gDescriptorMap structure is initialized below in
// codespace.
