Hello! > 1) The atusb_xmit function is only called *once* and then never again I just managed to fix this problem, too. I did configure the interrupt of the microcontroller in the firmware incorrectly. So i did never get an interrupt and the kernel was never informed that the frame was transmitted successfully (atusb_tx_done was missing) I will send you the link to an updated patch once i've tested it a bit more. -- Josef Filzmaier -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
