Speedlink SL-6502 PSX2 Gamepad Converter button remaping?

Hello,
I recently bought the SL-6502 PSX2 Gamepad Converter
and installed the latest WinXP drivers (sl-6502_03_07)
from the drivers section speed-link home site (Same as
the ones in the enclosed mini-disc)

The converter works perfectly with my standard SONY
PS2 gamepad, but I have a few queries concerning the
button setup and properties.

If I run “Game Controllers” from the WinXP control
panel, the default button state designations are as
follow (By pressing / testing the buttons on the
gamepad):

Button 1: Triangle
Button 2: Circle
Button 3: X
Button 4: Square
Button 5: L2
Button 6: R2
Button 7: L1
Button 8: R1
Button 9: Select
Button 10: Start
Button 11: Left Analog Stick
Button 12: Right Analog Stick

What I would like to do is change the button
designation from the WinXP “Game Controllers menu” and
permanently assign them to:

Button 1: Square
Button 2: X
Button 3: Circle
Button 4: Triangle
Button 5: L1
Button 6: R1
Button 7: L2
Button 8: R2
Button 9: Select
Button 10: Start
Button 11: Left Analog Stick
Button 12: Right Analog Stick

The reason I want to do this is because a lot of WinXP
games do not allow you to remap the gamepad keys to
suit my gaming needs and the default button
designations from the SL-6502 drivers are not ideal
for me.

My System:
WinXP PRO SP-2 English
Intel Core2 Duo @ 2.4GHZ 4MB Cache
ASUS P5B-E M/B 8-USB ports (The SL-6502 PSX2 Gamepad
Converter is connected to the front USB port)
2GB DDR-2 PC6400 800MHZ
Sound Blaster Live 5.1! (PCI)
Nvidia GeForce 7950 512MB PCI-X
SeaGate 500GB SATA-II 7200RPM
SeaGate 500GB SATA-II 7200RPM
SeaGate 500GB ATA 7200RPM
ASUS 16X DVD-ROM
Plextor 18X DVD-Recorder PX-810SA

So, is there any way to change the default button
designations from the SL-6502 WinXP drivers?

Thanks in advance.
