How to connect front usb ports

The presence of USB ports on the front panel of the system unit is a very convenient solution. Usually these ports are connected, but in some cases – for example, when assembling a new computer from components – these ports have to connect yourself.

Instruction

1. Disconnect the computer from the network. Press the power button, this will reset the charge on the capacitors of the power supply. You can now connect the front USB ports.
2. Remove the left side panel of the computer (the computer is facing you). On the motherboard look for a small yellow or blue connectors, they usually are in the lower part.
3. Each such connector has two rows of pins (needles): a par five, in another four. Let's call the left or right side of the connector where there are two pins, side "A". Second, with one pin.
4. Five pins, starting from "A" have the following mark (in series): VCC1 +5V, Data -, Data +, Ground 1, NC.
   The latter conclusion – NC – not used.
5. The four pins of the second row, starting from "A" have the following mark (in series): VCC2 +5V, Data -, Data +, Ground 2. The fifth output (pin) in this series no.
6. Consider the connector on the end coming from the USB port of the plume. It should be the inscription: VCC1, Data 1 -, Data 1 +, Gnd 1. The labels might be slightly different, but to understand just on the first slot under the pin is always specified by VCC or +5 V, the last Ground or GND.
7. In most cases, the wires of the connector have the standard colors:
   +5V red
   Data - white
   Data + green
   GND black
8. Connect the connector coming from the USB port of the Flex cable to the socket on the motherboard to the row of five pins. The first side "A" should be connected to VCC1 +5 V. the Fourth – Gnd 1. The last fifth pin remains free. In the second row next to it is a pin missing.
9. For easy wiring you can use special adapters to prevent incorrect connection. They are suitable for the connectors on the motherboard, usually blue, with a small side and a key and allows you to connect the adapter in only one way.
10. The pins on this adapter are marked as +5V, P2-, P2+, GND. If you have such an adapter (they can be supplied with the motherboard), plug in connector Flex cable in accordance with the label, then insert the adapter into the socket on the motherboard.
11. Connecting all USB ports, close the side cover. If you still are not quite sure of the correct connection after switching on computer, connect to the front port of the mouse with a USB connector. If the mouse will work fine, then everything is connected correctly and it is safe to connect flash drives and other equipment.
