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 Cisco IP Phone 8800 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.
