Why are some USB ports upside down?
Most USB receptacles are mounted to a circuit board, and in general, the “empty” space in the connector is on the side towards the board. This means that the device plugged into the USB connector will be upside down, so you cannot view the indicator LED.

What is difference between USB A and USB C?
The USB-A has a much larger physical connector than the Type C, Type C is around the same size as a micro-USB connector. Unlike, Type A, you won’t need to try and insert it, flip it over and then flip it over once more just to find the right orientation when trying to make a connection.
Are USB ports become obsolete?

What happens if you plug in a USB the wrong way?

What is a standard USB port called?
USB-A

How many pins does a USB 3.0 port have?
USB 3.0 ports have 9 pins and have a transfer rate of 5 Gbit/s, but 3.1 versions have 10 Gbit/s. While not technically a USB 3 port, the USB-C connector supports USB versions 3.1 and 3.2 and can connect to USB 3 ports with the correct cable or adapter.
What happens when you connect a USB 2 to a USB 3?
USB connections are backwards compatible. That means older versions will work with new versions, but they’ll only work at their original speed. For example, if you connect a USB 2 hard drive to a USB 3 port, the transfer rate will be USB 2 speeds.
What kind of USB ports do you need?
Generally, you can plug standard devices like mice and keyboards into a USB 2.0 port, as speed isn’t a priority for them. But any devices that will transfer data, like an external hard drive, should be plugged into a USB 3 port for best results.
How can I tell if my computer has a USB 3.0 port?
USB 3.0 ports can be identified by checking the physical ports on your computer. If you see a blue USB port, it’s USB 3.0. It may also be marked on the outside of the port with either “SS” or “3.0.” USB ports can also be identified within the Device Manager.
