My dad has a new PC using Vista, and has a printer connected via a USB cable, and a USB bluetooth dongle to connect his Nokia phone for synch'ing.
Both seem to goto sleep, and require re-establishing connection or PC re-boot.
Any ideas? I've heard USB ports can turn off when not in use.
Note that they have the box unchecked that says Allow the computer to turn off this device to save Power, on the Power Management tab.
