A portable device or imaging device is a device that the Windows operating system displays as such in Device Manager. Typical examples include digital cameras, IC recorders, and image scanners.
If you prohibit the connection of portable devices and imaging devices, you can connect only USB-connected devices. Connection of all devices that use the IEEE1394 interface or other means for connection is prohibited. Even devices that connect via USB may not be allowed to connect if they incorporate multiple functions, as exemplified by multifunction printers. Some smart phones and other devices are multifunctional composite devices and their connection may not be allowed.
You can check if connection of a device is allowed by viewing the USB device logon window on Management Console and verifying if the device is recognized as WPD or is actually allowed in the policy settings.
If you uninstall a client (CT) while the connection of portable devices and imaging devices remains prohibited in the policy settings, the connection state may continue to show that connection is prohibited. In this case, connect the device and then select Enable in Device Manager.
