Cisco 8851 Administration Guide

Each USB port supports the connection of up to five supported and nonsupported devices. Each device
connected to the phone is included in the maximum device count. For example, your phone can support five
USB devices (such as three key expansion modules, one hub, and one other standard USB device) on the side
port and five additional standard USB devices on the back port. Many third-party USB products count as
multiple USB devices, for example, a device containing USB hub and headset can count as two USB devices.
For more information, see the USB device documentation.
