I am afraid that within the PSoC5 chip is only one USB hardware availlable. On the development kit is a second USB port which is made with a separate CY7C68013A chip.
Thanks for the reply. Another thread discussed this but a solution wasn't offered: http://www.cypress.com/?app=forum&id=2492&rID=82498.
Is being able to access multiple CDC COM ports over a single USB port within the realm of possibilities?
Last chance to answer that question is to create a MyCase and get help from Cypress. On top of this page Support & Community -> Technical support -> Create a MyCase.
