Choosing a USB solution for your project.

Here are the important criteria to consider when deciding which solution to choose for your project. Some are more obvious than others. Please add to this list.

General.

• Do you already have the skills or can you transfer existing skills to this solution?
• How well does the product fit the specification of your project?

The Chip.

• Can you get free/cheap samples?
• Are they available in small quantities?
• Are they available in a variety of physical packages (your project may require a small QFN for production but a DIL for breadboarding).
• Is there a discount for quantity?
• Does it have an MCU to drive the rest of your project or is it just for the USB side?
• Are there royalty free drivers?

The Development Environment.

• Do you have to make your own? Is there one available off the shelf?
• How much does it cost?
• Is it mature?
• Is there a large existing codebase?
• Can you learn how to use it from out-of-the box working examples then adapt those to your needs?
• How well is it supported by online forums, IRC channels?
