This article briefly describes the Upgrade Your USB Hub (1N5400). This principle is easy to understand, but also very practical. Depth understanding of circuit elements, can be more effective to grasp this principle. Do you know the circuit, you can see and purchase these components: 1N5400 .

Problems can arise withUSBhubs that are powered from a PC when gadgets plugged into them draw too much current. This is often the case with devices fitted withUSBcables that are too long or too thin, causing voltage drop. There’s no need to scrap your oldUSBhub, however, if you upgrade it using this little circuit and an external power supply. Just cut the 5-V power wire of theUSBcable inside the hub and solder a diode (D1) in the pass-through direction. Now connect the 5 V wire from the external power supply to the cathode of this diode. D1 prevents any current from the power supply from flowing back into the PC.
