    CY7C65642-48AXC can this act as full speed hub only

    andrew.pettifer

      Hi we use the CY7C65642-48AXC high speed USB hub on our product.  We have a strange requirement that requires the upstream port on this device to run at full speed only.  Can this be configured by pin strapping / or otherwise without the upstream device having to be full speed only itself.  i.e. if the PC upstream is high speed capable but the the hub is connected and only responds to full speed (i.e. it does now do the high speed chirp!)?

         

      This is to allow us to easily fix a very specific problem we experience with high speed we see with a particular super speed monitor hub (very specific to our product so will not go into irrelevant detail here).

         

      Thanks
