Your Guide to Identifying USB Ports on Your Figurer
Step one: Know What a USB Port Looks like
There are two types of USB ports included in computers today.
- USB – A — The first and most mutual type is the standard rectangular-shaped port (commonly known as USB-A). They're commonly found in desktops and larger-sized laptops.
- USB Type-C — Another type is the oval-shaped Type-C port. Due to its smaller size, they're typically included in slimmer laptops like the newest MacBooks and the Dell XPS series.
Unlike USB-A ports, Type-C ports are symmetrical. This only means that yous will be able to connect a Type-C USB cablevision or device without worrying nigh its direction.
In that location are other USB standards (like MicroUSB) that are commonly used, but they're plant more in mobile devices like smartphones and tablets, not computers.
Step 2: Know the Types of USB Ports
USB has had multiple iterations since its inception in 1995. The principal differences between the various USB versions are its transfer rate and the corporeality of power they tin supply.
Transfer rate definition: Transfer rate is the maximum rate in which the USB device is able to transfer data from one end to some other.
Here are the current USB port types that are currently in use and their transfer rate:
- 1.0 (1995): 1.v Megabits/second (Mbps)
- 1.1 (1995): 12 Mbps
- 2.0 (2000): 480 Mbps
- 3.0 (2008): 4.8 Gigabits/second (Gbps)
- 3.1 (2013): x Gbps
USB 2.0 ports are uni-directional, which ways that information technology can only send or receive information, merely never both. USB 3.0 updates this standard and allows for simultaneous sending and receiving.
Some other difference between the different versions is the corporeality of ability they can deliver. USB 2.0 is capable of delivering upwardly to 500mA of power, while 3.0 tin deliver up to 900mA.
What this means is that the newer the port, the more energy it tin can bring to a continued device. A device where this is relevant is the external difficult bulldoze, as a 3.0 port would no longer require a hard drive to have its ain ability supply included.
The Type-C USB connector, also based on the three.1 standard, tin support up to 100 watts of power. This enables Type-C cables to charge laptop batteries, and not just phones and tablets.
Type-C devices as well support video input and output. With Type-C ports in identify, in that location's no need for dedicated video display ports like HDMI and DisplayPort.
Step 3: Check the Labels on Your Device
Manufacturers sometimes label the ports with what USB port blazon they are. Check for any labels on your ports that are marked as 1.0, ane.1, 2.0, 3.0, or iii.ane.
The version number specifies how fast USB devices can transfer files. A USB port with just the USB symbol labeled is typically a USB 2.0 port.
If the USB port has "SS" (or "SuperSpeed") on its label, it's a USB 3.0 port. If information technology's "SS ten", it's a USB 3.ane port.
USB ports with the lightning symbol on the label indicate a port that's "Ever On". This ways you tin can hook devices to charge your device fifty-fifty if the chief device is turned off (so long as it'southward connected to a lower source).
These USB ports can as well evangelize more power than other ports, which allows devices to exist charged faster.

- Next, look for the words "xHCI" or "Extensible Host Controller Interface". In this instance, the USB port is version 3.0.
In other cases, the port might also be labeled "USB 3.0" or "USB three.1" straight abroad. This makes it easier to know what type of USB port it is.
Step 6: Look at What Color the USB Port Is
While this is no longer as reliable as it one time was especially in newer devices, there is a color convention for dissimilar versions of USB ports.
- White USB ports are USB i.0 or USB i.1
- Black USB ports are USB 2.0
- Blue USB ports are USB iii.0
- Cherry-red USB ports are typically USB 3.1
- Yellow USB ports indicates a port that'southward "Ever On"
