Starting in the next SDK, we will have updated the USB drivers to default to WinUSB. The current NETMF Interface drivers will be included in the installer as legacy drivers, but they will not be used by default. If you have trouble with WinUSB, you can fall back to the legacy drivers.
Since USB drivers are so important to the SDK, we’d like to release them as a beta first to make sure everything is stable and solid. Please download and install the following based on whether your operating system is 32bit or 64bit and let us know about any problems or issues you encounter with them.
