USB Won't Connect
USB ports are not recognizing any USB device when inserted into the port. This could be from quickly and repeatedly inserting and removing a USB device and doing so without disconnecting the device through your computer controls first. Also you can prevent this from happening in the future by “Safely removing” the USB from the port instead of pulling it out.
Loose USB port
The USB port may have some “play” in it from constant use meaning, it wiggles around inside the computer and therefore may not be allowing a strong connection to the computer.
Broken USB port
There is something physically broken with the USB port: the USB port is bent inside, not allowing a device to be inserted or something is lodged inside of the USB port. If this is the case, you will need to access the USB port inside your laptop to either clean it or replace it.
Undetected USB device
If nothing physically seems wrong or broken with your USB port, it may be a software issue. First, go to your device manager to see if you have any hardware changes/updates. If so, do so and then restart your computer. Second, you may need to disable and then re-enable the USB controller.
