Top 5 Points That Clearly Make Differences Between a USB Port and a USB Hub

USB Port

USB also called Universal Serial Bus, is the standard interface, used to connect, interact and share data between personal computers and electronics devices. This interface not only communicates digital data over short distance electric wires but also can charge the electronics devices at the same time. USB interface can be further divided into two types. One is wired USB and other is Wireless USB. Only the wired USB has ports and cables. Wired USB can be further classified into USB-A, USB-B, Micro USB and USB-C depending upon the physical structure.

Differences Between a USB Port and a USB Hub:

Technically USB port and USB Hub almost share the common functionality. They are alternatively called repeater,hub,usb3.0,USB Type-C,USB HUBS, but there differ by following points,


The USB port is a way of digital connection between two end to end devices. For example, for host PC system you can connect a mobile phone to share data between them. Whereas USB hub hosts multiple ports, within a single box, to expand connection for multiple devices. For example, you can connect a smart phone, camera, keyboard, speakers, printers and much more, to a single host via USB hub.


The data transfer speed of USB hub is much higher than a single port. Because USB hub is dealing multiple ports, corresponding devices and data simultaneously.


A typical USB port draws a current of 100mA to 500mA, whereas USB hub draws the collective amount of current for all ports residing on the hub.


A USB port can only connect two peripheral devices. It cannot recognize/ control the flow of data between two ends. Whereas some latest version of hubs also called “sharing hubs” can allow multiple PCs to connect to same peripheral. It can recognize and control the flow of request between different PCs and that end. Depending upon request it can identify that which PC has recently made a request to that peripheral. In the same way, it diverts requested data to the same PC which made a request for it. Hence it serves a way to use the same peripheral for multiple users at any organization. A typical example includes USB Server & Printer Server. It serves as a common printer over the same network for different employees. It translates USB protocol to network IP protocol so that data can be broadcasted within the same network.


A USB port possesses a simple design having two ends to be connected between two different peripherals. Whereas Hubs may have very complex design depending upon the number of ports and other peripheral support like SD or TP card slot or HDMI output slot etc.

Typical Example

Nowadays, hubs have been evolved to provide a lot of solutions within the same device. Like QacQoc GN30H Premium USB-C Hub, which is not only the power supply source for various USB – C devices like MAC Book, Chrome Book etc, but also acts as super speed USB 3.0 data transmission device. It also includes slots of TF Card, SD cards, Ethernet port and 4k HDMI outport port.
