That's my problem, the keyboards are identical models and the only thing 
will distinguish them is the slot they are plugged into. I haven't got 
as far
as plugging both in and looking if there is a correlation between the 
provided by lsusb and the Alsa slot id. I think I can get them on 
separate hubs
which might be useful. I know very little about what goes on when 
devices are
initialised. If all else fails, I'll have to plug one into an Arduino 
and use
that to shift the channel number, but I had hoped to avoid going that far!
