A USB connection is a type of physical connection that allows devices to communicate with each other. USB stands for Universal Serial Bus, and it is a popular type of connection for many different types of devices, such as computers, printers, and external hard drives.
There are a few different ways to check if a USB connection is working properly. One way is to look at the device manager. The device manager is a utility that shows you all of the hardware devices that are connected to your computer. If a USB device is not working properly, it will be listed in the device manager with a yellow exclamation mark next to it.
