The USB port is a high-speed port which allows you to connect USB
peripherals, such as a mouse, an external keyboard, additional
storage (external hard disks), or any other compatible device.
Two USB standards are currently available on Acer computers: USB 2.0
(High-speed USB) and USB 3.0 (SuperSpeed USB). USB 2.0 ports on Acer
computers have a black tongue in the port, while USB 3.0 ports have a blue
tongue. For best performance, USB 3.0 devices should always be plugged
into USB 3.0 ports. Consult your device's documentation to see which
standard it supports.
You can also charge devices such as tablets, smartphones, or other
devices through a USB port. Some USB 3.0 ports support charging
devices when the computer is in Hibernate or turned off. Additionally,
you can use a USB hub to connect multiple devices to a single USB
When removing a USB storage device, you should right-click on the
USB icon in the Windows task bar and select "Eject <device>" to tell the
operating system to stop using the device before removing it. Failure to
do this may result in data loss or damage to your peripheral.
