[cisco-voip] Cisco 9971 and iPhone? .

I would imagine we restrict it due to the additional power requirements
as the 9971 is already a class 4 device. You could try to plug the phone
in with an AC adapter for power rather than POE. The PM that could
answer this is on PTO this week, but I can ask next week.

The USB camera we use is special as it contains more than just a camera;
it contains the engine that does the encoding of the video (unlike
regular USB camera devices which rely on computer processing). This
reduces the load on the 9971 when using video.

I know Cisco said you can't just plug any H.264 camera into the backside
port as there is hardware H.264 device, which makes me wonder if they
are doing something special with USB such as driver signing, cdp, etc to
limit those ports to Cisco only devices.

Just trying to hopefully use the USB port to charge my iPhone but it
saids it's been detected but disabled by admin.

Been through all the settings I can find so far.. is there something to
enable to get it to work?

Thanks, Erick
