DA - sounds like your modem is shot or as HA says cable is shot! You are getting power to the modem - the card reader showed you this. Sounds like a shiny new modem is a good idea to me! You can swap and change USB devices between ports and whatever your plugging in should be recognised - If you look under the devise manager you can see all the USB ports are under one heading. Go to Pc world and pick up an ADSL external USB modem. This should come with a power adapter to plug into the wall. Problem solved - you will have power to it 24/7!
