The problem is connecting the arduino uno to the PC (device descriptor failure), I tried to install the Chinese firmware, but it didn’t help?

Question

Arduino

I must say right away that I was looking for a solution on the internet, namely I did: I updated all the drivers from the "USB Controllers" section and unchecked the energy saving checkbox everywhere, put the firmware ch341SER.INF. In theory, after installation, a successful installation should be written, but what appears in the picture appears .

Answer 1

Well, it says that the driver was successfully installed. What is the problem? Are you sure you have CH340. There may be options. When you connect an arduino, do you get a COM port?
