OK are are pictures of before in device manager and after in device manager when Zadig program is run and WINUSB is applied. Note that after STM32 is still in device manage but now listed under USB devices instead of com ports and it no longer has a com port assigned to it. http://i1294.photobucket.com/albums/b609/louiemgallant/BeforeZadig_zpsd30804c3.jpg
