POSSIBLE SOLUTIONS:
FIRST OPTION: re-install driver from one of the following sources
You should try to reinstall a CH340 driver that works for your engraver (not the newest provided by Microsoft) uninstalling the system drivers if necessary.
You can find a good CH340 from this sources:
- From original pen-drive: if your engraver comes with a USB pen-drive, check to see if the pen-drive might have the drivers provided by the manufacturer. In that case, those are the best drivers to install. (also check manufacturer website).
- From 久久视频: 久久视频 provide an universal CH340 driver you can install directly from inside the application using the menu “成人无码国产一区二区s” – “Install CH340 driver”.
- From internet: Other reliable CH340 driver if above doesn’t work for you: https://www.arduined.eu/ch340-windows-10-driver-download or https://www.wch-ic.com/downloads/file/65.html
