Hi all,

   

 

   

I am looking to have my PC enumerate two separate USB UART ports using Cypress' PSoC 5LP development board. I haven't found much documentation on how I can achieve this using a single USBFS block, and using two separate USBFS blocks on Creator 3.0 gives be this error. I was hoping someone could point me in a direction. 

   

 

   

Many thanks,

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.

Hi Bob,

   

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?

   

-Thanks

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.
