Your tip helped me fix my problem also. Had the same problem with the usb_open error -12 when trying enable the software bias tee driver. Uninstalled the original driver, and then followed your steps (List All Devices >> Ignore Hubs or Composite Devices >> Selected RTL >> Install >> Voila!). Thanks ...
