The use of a powered USB hub was used to try and get over the error 650 but didn't work, the port will still limit the power if not used, I as well as BT thought it would fix the problem, but it didn't. The only fix to the power problem is to keep the USB port busy by checking for emails,
Also the 2 hour disconnect is if you haven't use the service for 2 hours then it will disconnect, by checking for emails you will never be disconnected.
