I am evaluating the PSOC 6 family to replace and existing design using a different micro controller. I need a composite USB CDC device which supports 4 comm ports. The psoc creator supports composite devices, but has insufficient endpoints to support 4 CDC devices. Is there a solution to this? Is the number of endpoints limited by hardware or the USBFS design?
Yes, we have created a solution before where we have 4 COM ports using all 8 endpoints, but it was designed for PSoC 4L.
I would recommend you to create a MyCase requesting this solution for PSoC 6. If you provide more info about the opportunity and the estimate units for mass production, you might get some help.
