Switching between two joysticks

[Mark Fraser]

I have two joysticks that I use on my computer:
1)  the main one is cordless and I therefore leave the receiver plugged into a 
USB port at the back of the computer permanently (/dev/input/js0)
2) analogue pad that I bought for my daughter as she can't use the joystick 
yet which I plug into a USB port on the front of the computer when needed 
(/dev/input/js1)

Trouble is, with the games I've used so far there doesn't seem to be anyway of 
selecting which joystick is used and always defaults to the cordless one 
(js0). Is there any way of temporarily selecting js1 when it is plugged in?
