After every reboot (new kernel), I have to go in to Powertop to change
the USB receiver for laptop mouse and stop it going to sleep. Is there
any way of making the change permanent?

When I make the temporary change, it flashes up at the top of the console...

>> echo 'on' > '/sys/bus/usb/devices/5-2/power/control';

It changes from echo 'auto' before changing the device to "bad".

If that is all it does then you could put that line into
/etc/rc.d/rc.local (making sure rc.local is executable as owner-group)

Off hand, I think the easiest way would be to use rc.local.

As root, "touch /etc/rc.d/rc.local" "chmod a+x /etc/rc.d/rc.local", then edit
the file and append the line ...
echo 'on' > '/sys/bus/usb/devices/5-2/power/control'
to that file so the script is executed on every boot.

There are probably other ways to accomplish the same thing.
