How to Know What Usb Ports You Have
ten years ago, the tech world was only beginning to coagulate around a connection standard. Back so, beingness a technology person unsaid carrying a lot of different cables for your gadgets.
USB 3.0 was launched all the style back in 2008, simply some of u.s. nevertheless don't spot the differences between this iteration and USB 2.0. Since and so, USB became the universally accepted standard of connecting our peripherals. USB adoption was certainly encouraged by the adoption of the micro USB in the mobile realm, which annihilated any attempts at pushing for custom charging ports.
But even if today all USB ports look and behave the aforementioned way, there are some differences between them that are like shooting fish in a barrel to miss. For example, you might have noticed that your phone charges faster when you connect it to a certain USB port on your figurer. Or you might notice that just one of your ports will permit you lot to accuse your telephone while the calculator is turned off. Why does this happen? Yous might suffer from a classic case of USB 2.0 and USB 3.0 confusion.
USB 2.0 vs. USB three.0
There's a good reason why USB iii.0 gained a lot of traction right from the start. Manufacturers rushed to adopt this engineering because it'south exponentially faster than USB 2.0.
In terms of speed, the USB 3.0 port can theoretically transfer information ten times faster (up to 5 Gbps/due south) compared to USB 2.0 (480 Mbps). I used the word theoretically because the transfer speed is highly dependent on your configuration and the data cable that y'all are using. To exist exact, with USB 3.0, you'll reach practical speeds of around 300 MB/s while the USB 2.0-speed peaks around xl MB/s.
USB 3.0 is also ameliorate with ability usage. While USB 2.0 tin merely have 500 mA, USB 3.0 tin have in over 900 mA power. This will consequence in smaller recharge periods for your mobile devices if you're drawing power from a PC / laptop.
Check if your calculator/laptop has a USB three.0 Port
If you purchased a new computer recently, you definitely have at least one USB 3.0 port. Slightly older laptops normally have i USB 3.0 and ii USB 2.0 ports. Nevertheless, before you try to locate the right port, y'all should first confirm that you lot have a USB 3.0 port. Here's how:
On Windows
- Press Windows central + R to open up a Run dialog. Type devmgmt.msc and hit Enter.
- In device manager, whorl down to Universal Serial Bus Controllers and expand the driblet-down carte du jour. If spot a USB three.0 entry and a Host Controller driver, you tin safely assume that y'all have at least one USB 3.0 port.
On Mac
- Click the Apple tree icon in the top left-hand side section of the screen. Then, select Well-nigh This Mac.
- In the About This Mac window, select System Report.
Note: If you're still on OS Ten 10.9 (Mavericks) or below, click onMore Info. - In System Data, click on Hardware, and so expand the USB tab.
- Similar to Windows, the USB ports are listed based on their blazon. Confirm that you accept a USB 3.0 port past checking if an item has "USB 3.0" in the championship.
Now that you confirmed that you have a USB iii.0 port on your computer, let's figure out which one is information technology.
Identifying the USB iii.0 port on your Laptop / Estimator
If you take a USB 3.0 port on your system, it's proficient to be aware which port will requite you the meliorate performance. There are 2 main ways past which you can't identify your USB three.0 port: by the logo and past the port color.
By Logo
USB 3.0 was also marketed as SuperSpeed USB. Most manufacturers use the SuperSpeed USB logo to let you know that you lot're dealing with a USB 3.0 port. If you see the SS prefix in forepart the regular USB logo, you lot successfully identified the USB 3.0 port.
Note: If you own a brand new laptop / PC, your manufacturer might take removed the SS prefix from the icon. This is common among newer systems in which every port is USB 3.0.
Y'all might also encounter the USB logo followed by a charging icon. This means that the port is capable of utilizing USB 3.0'south superior transfer rates to charge your mobile devices faster.
If you're lucky, you'll detect that your computer will still provide power to this charging port while the system is turned off. This volition enable you to utilise this port similar to a wall plug an charge your mobile devices without having to turn on your computer.
Notation: Even normal ports that don't accept the lightning symbol are capable of charging your mobile devices. Only even if they are USB 3.0, their power is limited and the overall charging fourth dimension will be bigger.
By Color
The official guidelines for manufacturers using USB 3.0 ports it to apply a blueish colour for the inside of the port. This makes it easier to differentiate them from USB 2.0, which has a black or white inside.
Note: This guideline is followed by the vast majority of manufacturers, regardless of the USB three.0 port gender ( male person or female).
Decision
If y'all're wondering most astern compatibility, a USB three.0 product is fully compatible with a USB ii.0 port. However, the USB 3.0 product will exist limited to the speed of the USB ii.0 port, so any speed or ability advantages will non exist used.
It'south clear that USB 2.0 is slowly being replaced by newer, more powerful iterations of the USB port. In 2017, the promoter group backside USB announced USB 3.2. This technology is capable of treatment multiple lanes of data at the aforementioned time, which translates into even more transfer speed.
But tech giants are already preparing the ground for the new universal standard. USB-C is expected to become the single port that volition charge and connect our phones, laptops, consoles in the near time to come.
As well, go on in mind that if you withal can't able to detect which ports do you have on your estimator but head over to the product page of your laptop/motherboard and they should have all the specifications over at that place. If yous don't have a USB three.0 Port on your estimator you tin really buy PCI cards that includes USB 3.0, Just populate your PCI slot with one of those cards and you should have the USB 3.0 ports now.
