Thanks for posting! If your device enumerates as USB Serial Device then you are missing the drivers from TDK-Lambda.
USB Serial Device
There are two solutions to the problem above. The first is to install the device drivers for your Genesys Plus. Once installed, your device will enumerate as G serial port as shown in the screenshot below.

If you can't install the drivers, the second solution is to configure Driver Framework to treat the device as a serial port. This can be done in the CMC Configuration Manager. The specific setting I changed was communication protocol from USB to Serial (RS-232). See the screenshot below.
