Automatic Removal of Unused USB Devices
When you connect a USB phone to the computer a new USB device is created in
the Windows registry for each phone. A large number of such devices can cause
Windows to run slowly. Emma has a feature for automatically removing unused Sony
Mobile USB devices. The feature runs in the background at regular intervals and
removes unused devices if the total number of unused devices exceed a specified
limit. The interval and the limit can be changed.
