Hello MDL! I'm having a blast with some profilic drivers on Windows 10. It's a simple USB to COM interface... but profilic didn't added support for it in the newest drivers (which I belive that come with Windows 10) so it installs with an exclamation mark. BUT, I found out that if use an old old old driver version from 2008 that was signed by MS, it works without problem... till I disconect and reconect it.. then windows installs the newer driver again! There's anyway to FIX this issue? It's driving me mad! Thanks in advance.
