1. Do not use the rpi usb port directly, use a powered hub to power the station (but I also keep batteries in the station)- even if you cannot switch the port on and off 2. Ensure the usb cable to the station goes nowehere near power supplies or screens - route it carefully away from all sources of possible interference. 3. Consider magnetic rings for the usb lead - again to reduce interference issues
Following the above 'rules' my Fine Offset very rarely 'locks up', and in fact I cannot remember when I last had a problem - so have never needed to use the powered hub reset method. It seems to me that one is better solving the cause, or minimising the chances of lock up occurring, rather than focussing on recovery methods.
