A USB socket is one of the most recognizable types of ports on modern hardware. Those who have used computers for a long time may remember the need for specific ports for a mouse, keyboard, joystick and perhaps a parallel or serial port for printers. Now almost everything is connected via a single USB connector which can be found on laptops, desktop PCs and mobile devices.
The latest version of the USB standard is called USB-C or sometimes USB 3.1. This is the first major improvement in USB since the introduction of USB 3.0 in 2011. USB-C is not just about a new shape for a USB plug and cable but also has improved data transfer rates and power delivery capabilities.
Its reversible plug also eliminates a big problem with earlier USB standards. How many times have you fumbled with plugging in a USB device only to realize later that you were plugged it in the wrong way? This can lead to expensive damage. usb c socket is not only reversible but also symmetrical, so it can be plugged in either way with no issues.
How do I identify a USB C socket on my laptop?
Besides the fact that USB-C is more convenient, it can also carry much higher levels of power. This enables laptops to be charged at full speed while simultaneously providing an internet connection and connecting external devices such as monitors and docking stations. It can even support DisplayPort Alt Mode and Thunderbolt 3 when using the appropriate adapters.
Aside from the obvious physical difference between USB-C and older USB standards, you can identify a USB-C socket by looking at its pinout on a circuit board or by checking the type of device that is connected to it. For example, a USB-C receptacle will have a physical plug detection switch which pulls down both CC1 and CC2 on the plug when inserted into the receptacle. A USB-C cable will have a blue or dark red plastic plug with matching metal pins.
While you may still be using older USB devices that only have a USB-A or USB-B connector, most newer products are now only available with USB-C connectivity. This is especially true for laptops, tablets and mobile devices like smartphones.
So if you’re planning on replacing your old equipment, it’s worth checking whether it has a USB-C port as well. It may not just save you money but it could also help reduce e-waste. You can also check in Windows if your computer has a USB-C socket by selecting the View menu and then choosing Devices by connection. Look for the USB-C icon on the list of connected devices to determine which version of the USB protocol it uses. You can use this information to plan what cables you might need in the future. For those who have not yet made the jump to USB-C, it might be a good idea to invest in some dual-head flash drives that have both USB-A and USB-C connectors on both sides.
