FX2 EP2IN and jump table

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?

Also, in cypress's USBjmptb.a51, what does USB_Int2AutoVector equ $ + 2 mean?
