No. There is no test.
On Windows 7, when I plug the USB chord in, Origin Connection tries to sync immediately with the Origin.
The Origin switches to a black on white display:
"Origin is currently controlled by an external application. Please wait..."
while the OC shows a round bouncing scroll bar (the title of the dialog window at this moment is "Syncing with Origin").
The percentage remains 0% all the time.
After a while, an "Error" dialog box appears that displays "Origin has been disconnected".
Clicking OK, I get the message "Can't load Origin preset infos".
And the display on the Origin remains unchanged: I have to switch it off and on to quit the black on white display.
