For an in-kernel solution serial-core would be to modified with a create parameter that says don't make a user space device. Then when the line discipline is registered on a hidden device make it automatically active. FTDI driver USB ID array would get a parameter for line discipline. If parameter is non-zero create the device in hidden mode and set the line disciple. Probably easier to just make new hardware with a real USB implementation on the chip. Like the CC2531. But then I'd have to program an 8051. -- Jon Smirl jonsmirl@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
