11 Connecting USB devices
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.
