In certain situations or scenarios it may be preferable to disable a USB port or all USB ports on a Polycom VVX Business Media Phone
Either the top USB Port or the bottom USB Port (compatible phones) or both can be disabled.
Using either
feature.usbTop.power.enabled="0"
or
feature.usbRear.power.enabled="0"
or a combination of both will disable the USB port(s)
