RemoteSensor is a wireless thermo- and hygrometer with an USB port on the receiver. You can draw fancy diagrams of temperature and humidity for up to 16 wireless sensors.
RemoteSensor is a more advanced example because it utilizes an interrupt endpoint to indicate to the host when new data arrived, demonstrating how AVR-USB handles a second endpoint. The receiver part is basically a serial to USB converter with special processing for the wireless protocol such as data integrity checks and data block buffering.
