    FX2 switch between USB addressed and configured state

    kysti.mlkki

      Regarding the now obsolete CY7C68013 part (not -A). Is there a way to change the USB state machine from adressed to configured without it receiving the "Set Configuration" request. Appears that logic for non-zero endpoints is enabled only after receiving that request.

         

      Actual design is for CY7C68013A, seems it does not disable endpoints the same way.

           Hi,

             

           

             

          EP0 is the defualt endpoint that is supported by all the USB devices. It is configured before any descriptors are even requested. Set COnfiguration request comes after the various descriptors are passed over to the host in response to the various GET_DESCRIPTOR requests. I did not fully udnerstand what is the issue that youa re seeing with CY7C68013, and what you want to achieve.
