The Eid-reader is on port 3 and the wifi-interface is on port 4 (both are connected to the same usb-hub). After some time
the wifi-interface gets disabled. The Eid-viewer is however never able to detect the card-reader. I looks as if this software
can't interface devices which reside on an usb-hub. How can I diagnose this?
