http://www.darkain.com/nintendo_ds/usbcable.php Here is someone taking the plunge with there Nintendo DS cables. But after someone gets a powered USB hub connected and plugs in there 770 and keyboard. Will it need a driver? Someone who already has a 770 needs to do this test. i am still waiting for it to be finish being delivered into my sisters hands on the other side of the world, then be sent to me on this side.
