For example, if you shared local usb device, you can see all the necessary information in Activity log: date and time when device was shared, what TCP port was used in connection and if the device was shared successfully.
At any time you can verify all the changes in program (devices shared/unshared, connections establishment, errors , etc). All you need is to point your mouse directly to "Activity log" in the main window. Besides you are able to switch "auto hide" off by clicking
icon and "Activity log" window will be attached to main window.
Moreover all the program's activity is saved to u2ec.log file, which you can find in directory, where you have installed USB to Ethernet Connector.
