Hi Cypress Team,

We are using the CYUSB3314-88LTXC hub in our design, we have concerns related to UP stream connections. We have to communicate with the USB hub to the processor.

I am sending you a connection image, it is connection-1 and connection -2, could you please confirm which one is correct?

Hi,

Since the processor is on the same board as the hub and there is no receptacle or cable use, the SS lines need to be swapped. So please use connection 2 for the upstream port connection.

Best Regards,

Sananya

Hello,

I could not see the connection images, could you please attach them again? You could also check the CY4603 schematic as a reference for the CYUSB3314-88LTXC design.

Best Regards,
Sananya
