We will consider five proven ways to fix this USB port trouble, both the basic practices of PC users and the options that you can consider if your USB port problem turns out to be device driver related.
You must first pinpoint the source of your problematic USB ports. It can be due to your USB device (any damage/dent on its physical parts, especially the connector and USB port) and it can also be due to the required USB device drivers. Your USB ports can also be the source of the problem (any physical damage or disabled ports) and it can also be device driver related.
Now, let us consider the ways to fix "USB Ports Not Working" trouble in a succeeding order, from the basic practices to the options involving device drivers.
1. Check for Any Physical Damage:

2. Connect Your USB Device to Another Computer
This is another option to make sure that your USB device is not physically broken. Try to connect it to another computer and see if it will be detected this time. If the problematic device requires a USB cable, you can also try to use another cable just to make sure that the cable is not the one at fault.
3. Reattach It to Your Computer
If you already tried reattaching your USB device to your PC prior to your USB ports trouble, then try to connect your device using each of the available USB ports this time around. This option will fix your problem if it's due to incomplete interaction between your USB device and your PC.
However, if you notice that a message (ex. USB device not recognized, etc.) is popping up on your desktop every time you attach your USB device, then you can check option 5 from this list.
4. Reboot Your Computer
There are also cases where just reattaching your USB device will not let it completely interact with your computer. This time, reboot your PC and attach your USB device afterward. In addition, some PC users shut down their PCs, unplug them from the outlet, and wait two to five minutes before turning on the power. After doing this, they report that their PCs are able to detect their USB devices again.
5. Check your Device Manager
If you still have USB ports trouble after undergoing the options above, it's now time to check your Device Manager. Open it by clicking the Start button, right-click 'Computer' or 'My Computer', click 'Manage', and select 'Device Manager'. Look for hardware devices marked by red X-mark or yellow warning symbol.
a. Re-enable Your USB Host Controller or USB Root Hub:
If one or more of your USB host controllers or USB root hubs have red X-mark, then these devices are currently disabled. For each device, right-click the 'device' and click 'Enable' to allow them to function.
b. Install or Reinstall the Required Device Drivers:
Having devices marked with a yellow warning symbol indicates that you have an unknown device problem, and it could be due to missing, corrupted, or outdated device drivers.
You can try updating the drivers through the Device Manager, but if it will not fix your problem, you can try to install/reinstall the device drivers using your installation or backup CD. You can also try to search online for the required drivers in case you don't have an installation CD or if the reason for your trouble is due to outdated drivers. In this case, you need to watch out for the dangers lurking online such as spyware, malware, computer viruses, or the possibility of downloading and installing wrong or incompatible device drivers.
Another alternative that you can try is to use automatic driver update software that can aid you to download the correct and up-to-date device drivers not only for your USB device and USB Host Controller, but for all other hardware devices with missing, corrupted, and outdated drivers.
