I've been doing some prototype work with a bespoke Android development 
project that is going on. I am sending scancodes directly to one of the 
evdev (/dev/input/event11 in this case) to achieve certain functionality 
which works fine for the most part. The problem is, plug in a few USB 
keyboards or mice and the whole thing falls apart because the way Linux 
enumerates the event drivers differently I guess.

So what's the best way of exposing event codes programatically, so that I 
can determine the correct /dev/input/eventx to send my scancodes too when 
more than a few devices are connected? I cannot be the only person who has 
experienced this problem and surely there's a reasonably efficient way of 
working out which eventX to send my scancodes too? I've been looking at the 
getevent code. I only need to check to see if the compatible codes are 
there, then I can reasonably assume it's the correct event handler.

Any help would be great.

Cheers
