Usb Ports; Mobile Device Charging - Cisco 8841 User Manual

USB Ports

Note: Cisco IP Phone 8851 only.
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.
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.

Mobile Device Charging

You can use the USB ports on your phone to charge your mobile device if the device has a USB
connection. The following ports support USB charging:
Your phone continues to charge the mobile device while it is in power saving mode. When you
use your phone to charge your mobile device, the following conditions apply:
•
A short delay may occur before charging begins.
•
In some situations, your device will not display the charging icon. For example,
the icon may not display when the device is fully charged.
If you unplug your tablet and immediately plug in a USB headset to the phone, a 3-second delay
occurs before the phone recognizes the USB headset.
