I had to uninstall all of my previous COM ports that were listed in the Port section of Windows Device Manager. It tells you to use the Windows Inbox drivers if you're on Win10, which I promptly ignored because they obviously don't work well for our application. )ġ. (I downloaded the driver package that includes Win 7 and Win 8 both 32 and 64 bit versions. It's also important to note I had a fresh set of the Win 8 圆4 version of the STM32 files. So that is what eventually led me to uninstalling all com ports. I kept finding that after plugging in a FC it would add to my USB ports in but not show in Device Manager anywhere. So I started doing some USB hardware testing with USBDeview (great little tool for USB info.) and an online USB ID Database tool. It's important to note that all the steps below came AFTER I initially followed your suggestion for manually updating the STM32 drivers and finding they didn't show up in Device Manager at all.which was rather strange.

In case it happens to someone else or is worthy to adding to the info you've already given in the other thread, here is what I needed to do.

I got it (them) fixed but it was a combination of your suggestion and some sleuthing into USB versus Virtual Com Ports versus "VCP in FS Mode".
