PSOC usbfs limits number of CDC devices in a composite device.

[olpec_4123636]

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?

Hello,

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.
