USB support
The IP Phone 1165E has a USB port for connecting a USB keyboard, 
USB mouse, USB headset, and USB flash drive. The IP Phone 1165E 
supports powered downstream 1.1-compliant USB hubs, including USB 
2.0 hubs, if they offer USB 1.1-backwards compliancy. There are two 
levels of power for the USB port.
When you power the IP Phone 1165E through Ethernet POE, the IP 
Phone 1165E provides up to 100 mA at 5 volts for the USB port.
When you power the IP Phone 1165E through local AC power, the IP 
Phone 1165E provides up to 500 mA at 5 volts on the USB port.
Note: Current limiting can obstruct the working of complex devices 
such as USB keyboards with built-in hubs. If a hub is involved, use 
external power.
You can plug a USB flash drive into the USB Port of the IP Phone 1165E 
or on a powered hub connected to the IP Phone, and transfer files to and 
from the IP Phone.
