Only for Cisco IP Phone 8851, 8861, and 8865.
Your phone may have one or more USB ports. Each USB port supports a maximum of five USB devices.
Each device connected to the port is included in the maximum device count, including any Key Expansion

For example, your phone can support five USB devices on the side port and five additional standard USB
