I started my project using the USB adapter, and it functions without problems for the project.
BUT BUT BUT, USB adapters for datalogging is not stable enough, I have lerned from my Danish Vantage Pro friends, that they ALL have shiftet from USB to Serial.
I have now done the same, problem is that the USB port randomly disappear, and no data is logged, until the program is stopped, and the USB plug is removed and reinserted.
This is a general WINDOWS problem.
I have now been running with my Serial adapter for 2 months and I have never lost connection with the software, with the USB adapter, I would have lost it between 1 to 5 times.
So my recommendation is to use the serial adapter always, and maybe use the USB adapter for a separate testing environment.
