Open a terminal and navigate to the CH341SER-master folder.

For example, the location of the extracted file is in the “Downloads” folder, then enter into that folder using the command:

cd Downloads/CH341SER-master

If you look, some files like this:

neon@linux:~/Downloads/CH341SER-master$ ls -l
total 92
-rw-rw-r-- 1 neon neon 35395 Jul  2 00:08 ch34x.c

Use the following command to compile:

make

After that, you will see there are files created.

Then use the following command to make load:

sudo make load

Replug Device
After this, replug the device and reload the application you are using. In the example of this article, I used the Arduino IDE application.

If it doesn’t appear, please logout/reboot your Linux operating system.
