Second printing, it is recognized immediately by GNU / Linux (Ubuntu). Just then a few seconds in Preferences-> Keyboard Shortcuts to configure all media buttons: play, next track, less / stronger, email etc. Impeccable!
Finally, it makes less noise than a basic keyboard, but is not completely silent either (unlike new Mac keyboards for example). It gives almost the same impression that a laptop keyboard.
In short, for the price (under 10 euros!) This is an excellent keyboard, with a beautiful design and comfortable to use which I highly recommend.
