Just use the others. You can get a 4/5 port extension that fits into any one USB (Working Port) for a few dollars. Each port allows additional USB devices to be added onto the original single port. Assuming you have TWO active ports, that translates to 8 USB ports min. Tiger Direct has them cheap.

Perhaps the laptop port is designed for a usb 3.0 insert instead of a usb 2.0? Also try using compressed air to clean both connections. The hub male end and the laptop female end.

It may have a manufacturing defect. Have you tried it on another computer? If it works on another computer, see whether it works when connected to a different USB port on the laptop. If it does, then you may have a bad or damaged USB port on the laptop. If it works on another computer but still does not work on the laptop when connected through an alternate port, then see whether some other device will work when attached to the laptop's USB port. If neither the mouse nor the other device work when connected to a USB port, then you have a problem with the USB controller. If an alternate device does work when connected to the USB ports of the laptop, and if the mouse works when connected to another computer but does not work when connected to the laptop, then you have a software problem, and probably need to change the mouse driver in a control panel or setting in the operating system of your laptop.

If all the USB ports fail to function, then repairing them is difficult, as the problem will be with the USB controller on the motherboard. If one or two fail to work, but the other ones work, then you have the option of putting a USB extension port into the working USB socket and that will allow you to run several devices from the one port, or, depending on the laptop in question, you can get a USB adaptor PCIMCIA card or Cardbus card that will plug into the expansion slot on the laptop and will give you a more permanent USB solution.

For this to work, there must be at least ONE working USB port

If it does not work on your laptop, what error-messages do you get?
Does some other USB device work in the USB port on the laptop?
Do you have more than one USB port on your laptop?
Do any USB devices work in any USB ports on your laptop?

USB devices draw electrical power through the USB cable.

Sometimes, the power-output from a USB port on a laptop is _less_ than that of a USB port on a desktop computer.

Hence, there are "Y" cables -- connect to two USB ports on your computer, and to the USB device at the other end, to draw more current.

Which manufacturer of laptop?
Which model-number?
Which Operating System?
Do other USB devices work when connected to the laptop's USB ports?

make sure the driver is installed
