Hello! I have a problem with a newly purchased one Arduino nano v3.0 from CH340G . Namely, I wanted to install the drivers because the device was visible as USB2.0) Serial and did not detect it in the Arduino IDE. To this end, I downloaded the drivers from the manufacturer's official website...

ID does not appear to be valid. You can try to modify the .inf file of drivers and add your ID instead of one of the already entered in the file (you need to replace all occurrences).

Could you write something more about this ID? Is it important what I enter instead of the current one or can I give any text?

It looks like something is damaged unless you have changed the identifier yourself. The correct one is: vid_1a86 & pid_7523 you have: vid_1a82 & pid_7123 Select Change and change all vid_1a86 & pid_7523 to vid_1a82 & pid_7123, then install the drivers.

Ok I did as you said. I tried to upload the driver via 'Update Driver' but after selecting the directory a window appears: After removing the driver and reinstalling using the installer it displays 'Driver's install failture' and it probably happens that when I click 'install' the device is disconnected and connected automatically. Then the Windows driver auto-installer starts which blocks my installation

In the inf file, have you changed all the occurrences of vid_1a86 & pid_7523?

When updating drivers, do you choose the option of choosing the driver yourself from the disk? If not, it will turn on automatically. The device may be damaged, it would translate the changed identifier. If it is new, can it pay back?

Hello!

I have a problem with a newly purchased one Arduino nano v3.0 from CH340G . Namely, I wanted to install the drivers because the device was visible as "USB2.0) Serial" and did not detect it in the Arduino IDE. To this end, I downloaded the drivers from the manufacturer's official website and installed them without any problem. Unfortunately, the device is still not visible as COM Port. Moreover, my old arduino also ceased to be visible. I will add that I am using Windows 10 x64

The correct one is:
vid_1a86 & pid_7523
you have:
vid_1a82 & pid_7123

Select "Change" and change all vid_1a86 & pid_7523 to vid_1a82 & pid_7123, then install the drivers.

Topic summary

The discussion revolves around issues faced by a user with an Arduino Nano V3.0 CH340G, specifically regarding driver installation and COM port detection on Windows 10 x64. The user initially installed drivers from the manufacturer's website but encountered problems as the device was recognized as "USB2.0 Serial" and not detected in the Arduino IDE. Suggestions included modifying the .inf file to replace incorrect device IDs (vid_1a82 & pid_7123) with the correct ones (vid_1a86 & pid_7523). The user faced further complications with driver installation failures and automatic disconnection during the process, leading to questions about potential hardware damage and the correct method for updating drivers.
