Obtaining a vendor ID

A vendor ID is necessary for obtaining a certification of compliance from the USB-IF. The USB-IF is responsible for issuing USB vendor IDs to product manufacturers. The cost for issuing this number is US$5,000 per year. Additionally, the use of a trademarked USB logo to identify certified devices requires license fee of US$3,500 for a 2-year term. Some microcontroller manufacturers offer a free or low cost sublicense of their vendor ID for development/testing and limited production (generally under 10,000 units). Vendors offering this free service include: *
