Import temperature and switch on/off the heater with Rev

[-= JB =-]

I really haven't done any usb stuff yet except configure the port.  I  
have done some testing
with an internal modem using the serial port.  The only thing I have  
done with usb is list
the devices.  It is possible the only way to access most usb devices  
is to write a driver for
Rev to access the port.
