PowerSwitch provides 8 bits of parallel output intended to switch e.g. the power supply to electronic devices. The PowerSwitch firmware is accompanied by a command line tool for Unix to control the device. (The command line tool can also be compiled on Windows using minGW and libusb-win32.)
PowerSwitch is also a reference implementation for AVR-USB. If you want to use AVR-USB in your own project, download PowerSwitch and extract the driver from it. We decided to provide a very simple demo because it helps a lot to have a working example to start with. A more elaborate example with an interrupt endpoint can be found in the RemoteSensor project. PowerSwitch may be very useful by itself. If you have a server farm at your provider’s site, you can use it to reboot machines without manual interaction on the site. Contrary to e.g. USB to serial or parallel converters (which would have been a very tempting demo, too), this type of hardware is not available in the stores.
