For USB compliance, any USB product must have a unique vendor ID (VID) and product ID (PID). The OS uses this combination to determine what driver to load for a given hardware implementation The VID and PID are reported to the USB host in the USB device descriptor. A unique VID can be obtained from the USB Implementers Forum (www.usb.org). A product ID can be whatever a vendor chooses - but since the VID/PID pair determines what driver is loaded, the same PID should not be given to two different products. The TI Header generator utility will allow customers to “customize” the TI VCP solution by overwriting the TI VID and PID with their own as well as enabling them to change the “bubble” description that pops up when the device is first plugged in to the PC. For additional info on using this tool and the options available, please refer to both the VCP implementation guide (SLLA170) and the READ-ME Instructions included with the tool. This tool includes examples of exactly what the input format of the files need to be to generate unique reporting information.
