Connecting USB device
You can connect a USB device to your computer by inserting its USB plug (Type A) into the USB
port on your computer.
The first time you plug a USB device into a particular USB port on your computer, Windows
automatically installs a driver for that device. After the driver has been installed, you can
disconnect and reconnect the device without performing any additional steps.
Before disconnecting a USB storage device, make sure your computer has finished transferring
data to that device. Click the Safely Remove Hardware and Eject Media icon in the Windows
notification area to remove the device before disconnecting.
Note: Typically, Windows detects a new device after it has been connected, and then installs the driver
automatically. However, some devices may require you to install the driver before connecting. Check
the documentation provided by the device’s manufacturer before connecting the device.
Note: If your USB device uses a power cord, connect the device to a power source before connecting it.
Otherwise, the device may not be recognized.
