Tchibo Ecobutton

The [http://www.tchibo.de/is-bin/INTERSHOP.enfinity/eCS/Store/de/-/EUR/TdTchDisplayProductInformation-Start?ProductSKU=0021538&produkt=Ecobutton Tchibo Ecobutton] is a small USB-powered device / button which acts as a HID device (and also has three fancy green LEDs). The use-case is that you press the button to suspend your PC in order to save power.

== How it works ==

It's a USB HID device. When you press the button, the HID devices "presses" the '''Windows+R''' keys on your (Windows) PC, which openes the standard Windows "Run" dialog, then it presses the keys '''ecobutton''' and '''Enter''', i.e. it executes a Windows program called '''ecobutton''', which in turn does the rest of the work.

This device can easily be abused for other tasks, just provide an application named '''ecobutton''' which does whatever you want to happen at the button press. It's equally simple to do it on Linux or Mac OS X, of course. Just go into a console (or position the cursor in an xterm) and press the button. It'll invoke a program named '''recobutton''' (sic!) which must be in your path, as the '''Windows''' key is usually ignored on Linux.
