The 3206 is now not recognized on any USB port.
I tried another PC as well. Both PC are running XP Pro.
The PC looks for a driver and says it can not find one. The LED on the 3206 lights up and there is no difference if I use the external 3206 power supply.
The porblem started to happen after I introduced another USB port powered device on the same USB powered hub with the 3206. This caused the USB power to shutdown. I tried to resolve the problem by moving the USB loads around the different USB ports.
