USB connections
Just to avoid others to run into trouble...
With my constant drive to keep my system up-to-date (thank god my wife does not read PPRuNe) I have installed a 127-connector USB-hub. Works fine, no probs.
Have my laptop connected via USB to my PC, fast and reliable, fine.
Have my parallel printer connected to the USB hub, does not work. It took me about 4 hours with a tiny almost unreadable "manual" to find out that bi-directional data transfer (as my printer needs) will not work via the USB-parallel connectors available now.
Have one for sale now.....
