Ok, I do understand what you are saying, the heads are the same, the controller wont support it, etc.
To make this perfectly clear, the keyboard itself is plugged into USB2.0. Someone confirm that it is not possible to replace the cord to make the keyboard draw more power, or something, and I'll shut up...
What doesn't make sense to me, is that if the heads are the same, and there are such things as multiple usb 2.0s coming out of one usb2.0...and a new revision of the logitech G15 will have powered usb in the keyboard...why cant one simply draw more power?
