Thank you for your input, but there never was a driver for the FX5051. It was a strict plug and play system as noted on the Altec L.., website. Windows 7 recognizes the speaker system no matter what USB port I use, but when I use Configure in Sound properties. I can only get some, but not all the speakers to fire off. Sometimes when I remove the USB and reconnect, it may be another set of speakers that are working. It seems like the Windows is stuck in some 3.1 mode.
