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 USB port on your computer,  
Windows automatically installs a driver for that device. After the driver is  
installed, you can disconnect and reconnect the device without performing  
any additional steps.  
Note: Typically, Windows detects a newly connected device after connecting it, and then  
installs the driver automatically. However, some devices may require you to install the  
driver before connecting. Check the documentation provided by the manufacturer of  
the device before connecting.  
Before disconnecting a USB storage device, make sure your computer has  
finished transferring data by that device. Click the Safely Remove Hardware  
and Eject Media icon in the notification area of the Windows desktop screen  
to remove the device before disconnecting.  
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.
