Connecting USB device
Yo ur computer comes with three USB ports compatible with USB devices.
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 t
without performing any additional steps.
Note: Ty pically, 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.
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.
