Introduction
Commercially available USB peripherals can be easily and flexibly connected via the USB
interface. For example, you can connect an external USB keyboard and a USB mouse. If the
USB keyboard has a USB interface, you can connect other USB peripherals, such as a USB
mouse, directly to the keyboard.
USB interface
There are several types of USB peripherals:
•
Low power devices: maximum 100 mA power consumption, e.g. mouse and keyboard
•
High power devices maximum 500 mA power consumption, e.g. hard disk and floppy
drive
Note
The general USB specifications apply to the USB interfaces on the computer unit.
The USB interface on the front panel has been approved for a maximum of one additional
USB hub.
Using USB peripherals
Notice
When installing a USB device for the first time, make sure you have the required device
driver.

using the dialog "Unplug or Eject Hardware". For additional information, refer to the
