Thanks for the replies but its not the batteries nor focus.  It went 
wrong again last night so I did this.

- exit frontend
- stop lircd (if only because it eats the events so xev doesn't see them)
- run xev
- nothing
- rmmod mceusb
- modprobe mceusb
- xev shows remove springs back to life

I've got another machine which is very similar, same os, same receiver 
but the problem doesn't occur.  Swapping the receivers/remotes didn't 
change anything.   I don't suspend this other machine so much as its 
used less frequently so its usually turned off rather than suspended but 
still.  Makes me wonder whether its a bug in the USB hub driver as they 
have different motherboards?

Still it looks like rmmod'ing mceusb before suspend might fix things, I 
tried it and lircd died but I'm sure I can do something about that.

I'd be grateful of further input if anyone has any bright ideas :)

Cheers,

Chris.
