I don't think this is an issue for just the 3T, I think it's an issue with Windows 10.
Apparently, ever since an update last year, Windows 10 doesn't install unverified drivers even though the installation wizard shows a successful installation.
I've read that some people were able to fix this "fastboot devices" issue by installing the drivers after disabling driver signature verification in Windows 10.
Neo3D, have you tried installing the drivers (running the adb-setup) after disabling driver signature verification?
I think my issue is a mix of the above as well as some error I made in uninstalling drivers...?
I just want to remove all my adb/fastboot/3T related drivers and install fresh while in "disable driver verification" mode...thought Neo3D's tool or deleting them via Device Manager would do the trick, apparently not.
