I believe the KG900 is an external keyboard...
https://www.amazon.com/Alienware-Portuguese-Brazil-Keyboard-Y-U0008/dp/B00X6CJ4B0It seems that there are a few issues with this keyboard.
1. It doesn't work well with non-DELL computers.
2. There seems to be a different driver for different versions of Windows.
3. It takes TWO USB connectors to run this thing.
/e Seems similar to the Logitech G105
