On our Dell Inspiron 5160, we moved the laptop to another room. now when we connect the mouse or the printer, it doesn't connect. it doesn't make the little bell sound that it used to make when we plugged in a usb plug.
I'm not a great fan of USB ....ever since a USB external hard drive decided to become undetectable halfway through a back up once ....
Since the problem occurred after moving the PC, the first thing that comes to mind is that some wiring has come loose .... but as it's a laptop that seem hardly likely.
Have a look in Device Manager (Control Panel/System/Hardware/Device Manager) ....see if there are any yellow warning marks next to any of the USB devices.
One trick that often works in these cases is to uninstall all the USB Root Hubs in Device Manager (right click each one and select uninstall/remove), then reboot the pC and let Windows reload the devices. Don't ask me why ....but this works 90% of the time.

I tried your suggestions, but nothing worked. I have a feeling your intial instinct is right.. that something happened to the USB ports when we moved the laptop. Thanks for the help.
