But first I need to get at76_usb stable. please be careful with this. I have seen so many broken or vendor enhanced DFU stuff that it might be not a good idea to put it into the USB core since it would be full of quirks. I do have my own dfutool used for firmware flashing and the OpenMoko project got their own dfu-util. Both in userspace.
