TI recommends using the USB-IF Vendor Info File Editor (VIF Editor) tool to view and edit existing VIFs. VIFs can be opened and modified in generic file viewers that support .xml files, but the VIF Editor tool provides a GUI that makes sure valid values are entered for each of the fields and maintains the correct formatting of the VIF. The USB VIF Editor can be found at USB-IF, or by searching for USB Vendor Info File Generator in a browser. The download consists of the VIF Editor tool and the Vendor Info File Specification document, which contains additional information about the VIF and the settings. The VIF Editor tool is updated regularly, and users must generate VIFs using the latest version of the tool. TI's GUI VIF Generation Tool does not always generate VIFs according to the latest specification. When this is the case, users need to load the old VIF into the latest VIF Editor tool, make any necessary changes, and save the VIF from the latest tool to update to the latest specification. Figure 2-2 shows the USB IF VIF Editor front page and how to load a VIF generated from TI's Application Customization Tool into the VIF Editor Tool.
