Thanks for your work on this, Benjamin.

I have a followup question -- why not do this in the kernel completely 
though? I have actually been asked by Linus directly (so we'd rather do 
that :) ) to include pairing trigger as a sysfs toggle instead of having 
to use userspace utilitites, and it actually makes sense to me.

Are you aware of any particular reason to not have all that's provided by 
uLogitech in the kernel?

Thanks,
