    FX2 EP2IN and jump table

    hithesh.n

      I am using the fx2 to do HID mouse enumeration. So far, enumeration is ok. Windows recognizes fx2 as a hid mouse.

         

      But I am unable to send any data to the host. I am trying to use EP1IN end point. EP1IN interrupt is enabled.

         

      I think USB jump table might not be working.

         

      Here's how I have implemented the jump table:

         

      AUTO vector is Enabled in the INTSETUP register

         

      INT2VEC EQU 0900H

         

      CSEG AT 0043H

         

      LJMP INT2VEC

         

      CSEG AT 0900H                  ;start of jump table

         

      LJMP ISR_SUDAV

         

      CSEG AT 0928H                 ;

         

      LJMP ISR_EP1IN

         

       

         

      Any help/suggestions?
