How to switch an Output on when device is registered?

Hi there,
is it possible to switch an Output to High- State only when the avr-usb is succesfully registered at the Host- System?
I just want to use AvrUsb as USB to Rs232- Converter but the whole Circuit should be powered by USB-BUS at its consumption will be around 400mA, so i want to switch on/off the rest of the circuit with succesfull bus registration.
i wand to do that because i have read that the power consumption of bus slaves should be only 100mA when not registered (max 100mA) and only if succesfull registered it can go up to 500mA.
Sorry for my bad english, im from germany...
