PS2 wireless gamepad

Hi,
Im trying to interface my ps2(playstation2) wireless controller with pic16f688 using picbasic pro 2.46. I copied this code from BS2 and converted it to pbp. Serial communication to my pc for debugging has no problem, but buff(5) is always null. Here is my code.

@ DEVICE PIC16F688, WDT_ON
@ DEVICE PIC16F688, PROTECT_OFF
@ DEVICE PIC16F688, MCLR_OFF

include "modedefs.bas"
DEFINE OSC 8
DEFINE HSER_RCSTA 90h ' enable hardware serial port
DEFINE HSER_TXSTA 24h ' enable high speed transmit

' Set baud rate
DEFINE HSER_BAUD 19200
DEFINE HSER_CLROERR 1

PsxAtt vAR portc.3 ' PSX joystick interface
PsxClk VAR portc.2
PsxCmd VAR portc.1
PsxDat VAR portc.0

LED var PORTA.0

buff VAR Byte[9]
tmpout VAR byte
idx VAR byte
idy VAR BYTE

HIGH LED
pause 1000
Hserout ["Test",13]

GOSUB PS2Init 'Set up Playstation for analog

MAIN:

HIGH LED
GOSUB Get_PSX_Buttons
Hserout ["Byte5=",buff[5],13]
LOW LED
