You've got a hot new product, ready to sell - You're a pro now! But part of that professionalism is making sure you have signed versions of all your drivers. If you're using a FTDI or Cypress or SiLabs chip to do USB, you might already have a signed driver that comes with it.

If not, its an extra step and expense that will make your life (and your customer's lives!) much easier. These are my notes as I signed a Circuit Playground CDC driver file, made an installer, then signed that installer
