      Processor:      PIC18 or PIC24 USB Microcontrollers
      Hardware:       The code is natively intended to be used on the following
                      hardware platforms: PICDEM™ FS USB Demo Board,
                      PIC18F87J50 FS USB Plug-In Module, or
                      Explorer 16 + PIC24 USB PIM.  The firmware may be
                      modified for use on other USB platforms by editing the
                      HardwareProfile.h file.

  Summary:
    This file contains all of functions, macros, definitions, variables,
    datatypes, etc. that are required for usage with vendor class function
    drivers. This file should be included in projects that use vendor class
    \function drivers. This file should also be included into the
    usb_descriptors.c file and any other user file that requires access to
    vendor class interfaces.
    
    
    
    This file is located in the "\<Install
    Directory\>\\Microchip\\Include\\USB" directory.
  Description:
    USB Vender Class Custom Driver File
    
    This file contains all of functions, macros, definitions, variables,
    datatypes, etc. that are required for usage with vendor class function
    drivers. This file should be included in projects that use vendor class
    \function drivers. This file should also be included into the
    usb_descriptors.c file and any other user file that requires access to
    vendor class interfaces.
    
    This file is located in the "\<Install
    Directory\>\\Microchip\\Include\\USB" directory.
    
    When including this file in a new project, this file can either be
    referenced from the directory in which it was installed or copied
    directly into the user application folder. If the first method is
    chosen to keep the file located in the folder in which it is installed
    then include paths need to be added so that the library and the
    application both know where to reference each others files. If the
    application folder is located in the same folder as the Microchip
    folder (like the current demo folders), then the following include
    paths need to be added to the application's project:
    
    ..\\Include
    
    ..\\..\\Include
    
    ..\\..\\Microchip\\Include
    
    ..\\..\\\<Application Folder\>
    
    ..\\..\\..\\\<Application Folder\>
    
    If a different directory structure is used, modify the paths as
    required. An example using absolute paths instead of relative paths
    would be the following:
    
    C:\\Microchip Solutions\\Microchip\\Include
    
    C:\\Microchip Solutions\\My Demo Application

    Function:
        USB_HANDLE USBGenWrite(BYTE ep, BYTE* data, WORD len)
        
    Summary:
        Sends the specified data out the specified endpoint

    Description:
        This function sends the specified data out the specified 
        endpoint and returns a handle to the transfer information.

        Typical Usage:
        <code>
        //make sure that the last transfer isn't busy by checking the handle
        if(!USBHandleBusy(USBGenericInHandle))
        {

            //  endpoint USBGEN_EP_NUM

    Parameters:
        ep - the endpoint you want to send the data out of
        data - pointer to the data that you wish to send
        len - the length of the data that you wish to send
        
    Return Values:
        USB_HANDLE - a handle for the transfer.  This information
        should be kept to track the status of the transfer
