CPLD serial buffer problem

Hi,
I interfaced a USB 8 bit data bus with a CPLD. I made a 48 bit buffer (

ser_buff ). I am loading the buffer at each falling edge of the USB
clock. and then copying it into another 48 bit buffer ( Temp ) and the
serially ouputting the Temp buffer in another process running on
different clock. "inc" signal acts as a trigger signal to the other
process to start parallel to serial conversion.


The problem is that I am not seeing the right data coming out of the
CPLD ( ser_out) port. If kept the USB data to zero but at the ser_out,
I can still see some ones. Please adivce soon.
My code is given below


Thanks
John
