I can't find a fix for my problem. I know there is probably a forum for this. I thought I'd ask you about my problem I installed the CH340, (ch341); and all went well. NO errors in the device manager. BUT I get this error even with the built-in blink.ino A few months ago ALL work fine, but now I can't get ANYTHING to dump to my Nano. I did a complete deletion of Arduino and the CH340. I also blew away anything in the "registry", (yes I know what I doing in their)! I have 3 new Nano, so it's not them, and the Serial Port is correct...
When I click on verify, the following is what comes back immediately!!! Compiling Sketch: just says compiling sketch, and seems like it's hung up.
