;
; The example below places device and string descriptors, as well as 
; application firmware, into the header of an EEPROM to be used with TUSB3410.  
; Unlike with TUSB2136, TUSB3210, and TUSB5052, the firmware should NOT modify
; these descriptors programmatically, or it will overwrite the values below.  
; Assuming they are not overwritten, these descriptors will be reported to the 
; USB host.  
;
; For 3410 virtual COM port applications (USB/serial bridge), use this template and do the
; following:
;
; 1)  Customize the VID/PID in the device descriptor
; 2)  Customize the strings
; 3)  Prepare the serial number string for customization with an EEPROM 
;     programmer
;

;
; Commands:
; Header Generator uses these commands to generate an EEPROM header that is
; readable by the bootcode.  Check the bootcode listings for more information about
; how each descriptor block is handled.  
;
; USB_DEVICE_DESCRIPTOR,       
; USB_CONFIGURATION_DESCRIPTOR 
; USB_STRING_DESCRIPTOR        
; AUTOEXEC_BINARY_FIRMWARE,   
; END                          
;
; For string descriptors, '@' is used to generate SPACE character.  
; Therefore it is not possible to include an '@' symbol in the descriptor
; string.  
;
;
; Rules:
;
; 1. Before any descriptor blocks, create the device signature using DEVICE_NAME.
;    This is the part number for the USB controller device (i.e., "TUSB3410")
;
; 2. The last descriptor block for any config file should always be END.  
;
; 3. The header should contain, at a minimum, a device descriptor and string 
;    descriptors for manufacturer, product, and serial number.  Firmware can
;    also be included with AUTOEXEC_BINARY_FIRMWARE.  
;
; 4. USB_STRING_DESCRIPTOR type only supports one language ID.
;
;------------------------------------------------------------------------------
;
; Step 1 - Create device signature
;
DEVICE_NAME = TUSB3410       ; Tells the bootcode there's a valid EEPROM header
;                            ; Do not change if this script is being used with
;                            ; TUSB3410.  
;
;------------------------------------------------------------------------------
;
; Step 2 - Create descriptor blocks
