I am in the e-step upgrading Micro Swiss includes hotend to my Ender 5 Plus. And so I need to install CH340 to my computer (search CH341SER - Nanjing Qinheng Microelectronics Co., Ltd.). But then instead of “succesful install” the message came out “The drive is successfully Pre-installed in advance!” and there is no USB port setup as it is expected. Any one can help please?
Wish i could help, but hope you got it figured out.
