It's probably your USB ports. Plug your stuff in and go to devices and see what port it's now on. Needs to be COM 3-4. Sometimes it takes removing all USB, using the driver cleaner from Moates, install drivers, plug in cables and restart. Force them to Com 3-4 and everything else will find a way to work other USB ports. My Windows 7 changes between 2 of my 3 USB ports, never know which one. So try another port first, leave cable plugged in and restart, no connection? Try another USB port.
