Subject: /proc/bus/input/devices changing while booting

Hello,

while booting, an init-script on my machine greps the Handlers entry of 
a certain device (USB touchscreen) from /proc/bus/input/devices. It ends 
with "event2", so I configure my software to listen for events in 
/dev/input/event2. A few seconds later /proc/bus/input/devices changes, 
the order of the devices is different and the Handlers entry for my 
device ends with event1 making my device misconfigured and thus unusable.

Can anybody explain that behaviour? How can I get the final eventX 
device file?

I'm using kernel 2.6.28.8 on an Intel Celeron, chipset ICH5.

Regards

Stefan
