Yeah, on top of that :)
I just read a small part of the IEEE1284 (parallel port) spec. It is
possible to connect 20 devices to _one_ port by daisy-chaining and
multiplexing the devices. All in line with the spec! And all devices are
adressable.
At least two of the five possible devices in a daisy-chain will appear
sometimes in a HAL environment.
So we should do childs for it, if we find a device?
