Hi Claudio, first things first, don't top-post on the mailing list. It is a proper open source mailing list that uses bottom posting and inline quoting. > I'm using an arduino board and a ps3 gamepad to move 3 servos for a > small robotic arm.

You can grab one of my old presentation that I did around 2003, but even that might not help that much. It is a really complex system. Sorry, there is nothing I can really do in a quick answer. If you wanna look into the kernel code, look at net/bluetooth/ and include/net/bluetooth/. The actual drivers for the USB dongle is at drivers/bluetooth/btusb.c.
