Issues with USB Wireless Adapter drivers on Windows are typically associated with Windows automatically installing incorrect drivers. To prevent this from occurring on Windows, do not connect the DLUSB until after Commissioner is installed. To resolve, the correct drivers will need to be manually assigned per the step outlined in the Install Commissioner article.
Issues with DLUSB Wireless Adapter on MacOS are typically one of two possibilities:
