Interesting question, depends on the nature of the problem itself. If it is a hardware problem, then you simply cannot do anything with a laptop, unless you can get it sent back to the manufacturers due to the warrenty/insurance you got, and hope they can fix it.

If it is a driver issue. you go to the laptop manufacturers website and install the latest drivers from there or it that isn't working correctly, you would need to uninstall the drivers for that specific port, then use windows/update to auto-install the required drivers.

If it is a spyware/virus/software conflict issue. Great range of ways to deal with this. from reformatting your computer and clean installs, to adequate software to deal with the issues.

If it's happening with every USB port on the laptop then it's more than just a simple loose connection, but could be a more serious hardware issue.

It could also be software related - remote, but worth a try. Go into device manager and remove all the drivers for the USB root hubs and USB controllers. Reboot and let the drivers reinstall, then try again.
