The USB adapter with TP/FT-10 label on the top of it is actually the U10 USB Adapter (the name is shown on the label on the bottom). TP/FT-10 refers to the LonWorks channel type.
The OpenLDV Network Driver is used for the U10/U20 network interfaces.
Make sure the U10/U20 are not plugged into the PC when installing the driver.
To find the latest Network Driver go to www.echelon.com/support, click Software Downloads, type "openldv" in the search text field and hit the enter key.
OpenLDV 5.0 was the latest as of August 2015.
