Well it looks like the USB driver is correctly detecting the processor. Show us the settings you are using in Unity Pro or Control Expert

Were you able to connect previously? There was some issues where if i connected once and disconnect and take out usb and put it back and try to connect again it stopped working. Usually I had to stop the usb service from running and the it would work again. Or restart windows.

Make sure that when you plug in the usb cable in pc and plc that in your taskbar at the bottom right of windows a small icon with usb written on it pops up.
Normally there is always a modbus driver icon there but when plugged in a usb icon should appear as well

you should have on Unity / Exostructure these com settings selected:
Media : USB, address: sys.
If you have USB icon, of which Chud writes, it should be posible to connect
