As you've discovered, the G202 is 'plug and go' in Ubuntu and it's
worth noting that most USB devices are similarly detected and used
automatically. It's when the 'plug and go' doesn't work that it's
necessary to go looking for drivers or the fixes needed to get it
working - has to be said though that some USB devices will *never*
work in any flavour of Linux as their firmware is written to work only
with Windows. All down to the manufacturer here and nothing you can do
other than try a virtual Windows or use a different device.
