USB Ports
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
Modules.
For example, your phone can support five USB devices on the side port and five additional standard USB
devices on the back port. Many third-party USB products contain more than one USB device, and thus count
as more than one device.
If you use a USB hub and remove the USB cable from the phone during an active call, your phone might
restart.
