It is all about electronics. When the connections are properly made and there isn't any defect in that, then obviously current will properly flow and your device will operate properly.
Â
The problem that you are facing is only the front usb ports are not working properly. There can be many reasons for the front usb ports not working of which only the following two are most commonly seen:
Â
1. It can be possible that someone might not have connected the internal connections of the front usb panel to your motherboard. In this case you will have to open up your desktop computer and connect the wires of the front usb panel to the motherboard according to the proper connections and pins. You can get to know about the pin configuration of your motherboard by seeing the manual of your respective motherboard installed.
Â
2. It can also be possible that the connections of your front usb panel might have got shorted. In this case the only thing you will have to do is to replace your front usb panel with a new one.

As, you know everything is connected via wires in a CPU. So, USB ports are also connected to motherboard via wires.Â
The connection point of USB and motherboard is called Jumpers. Might be the connections of front USB ports are not done properly or they got brooked and connections of back USB are well connected that is why only back USB ports are working.

That’s because the USB ports at the back of your CPU are connected directly to your motherboard while the USB ports in front are not. They have to be connected to the board manually. The USB ports in front of your CPU are actually optional and don’t come with the motherboard. They were added as an additional feature of the CPU case manufacturer.
The USB ports in front have cables inside that need to be connected to the motherboard manually. It is actually not hard to connect the cables. Just check the imprint on the motherboard for the proper pin configurations. The pins for the USB ports are designated with their respective pin numbers.
You just need to find which cables belong to which USB port and connect them to its designated pin numbers. You might find the cables confusing because of the additional audio cables inside but when you do find the cables, it is very easy to connect. This task requires opening of the CPU case to properly view the cables inside.
