Chapter 3 Using Your MacBook Pro 53
To use a USB device with your computer, connect the device to the computer.
Your computer automatically detects newly connected devices and loads the correct
software to work with the device.
Note: If your MacBook Pro can’t find the correct software when you connect a USB
device, you should either install the software that came with the device or go to the
website of the device manufacturer to locate and install the correct software.
Understanding USB Devices and Battery Power
You can use USB devices, such as joysticks and keyboards, that are powered by the
MacBook Pro USB connection instead of a separate power adapter. However, these
types of USB devices can cause your MacBook Pro battery to be depleted faster. If the
device will be connected for an extended period, it is a good idea to connect the
MacBook Pro power adapter.
