How to Fix Arch Linux Permission Denied Arduino IDE STM32 Microcontroller

This is a problem that I got from my project of programming STM32 using Arduino IDE on Arch Linux.

All the equipment I have installed, starting from the STM32 Core library board, Libusb library, ST Link, accepts when I check in the terminal using the "lsusb" command. I am confused as to what causes this.

Linux Permission Denied Arduino

Permission Denied?

I just remembered when using ubuntu. You can read install Arduino Ubuntu Permission denied on this page.

I tried it on Arch Linux, but there is no dialout in arch linux. Finally I got it on Arch Linux we used "uucp" and it worked.

libusb couldn't open USB device /dev/bus/usb/001/006: Permission denied.
libusb requires write access to USB device nodes.

How to fix Permission Denied Arch Linux?

Are as follows:
There are two steps you must take. Open your Terminal.
1. Modify user accounts.

sudo usermod -a -G uucp <username>

For example your computer username is Asus, then you write:

sudo usermod -a -G uucp asus

2. Give the port permission to read and write using the terminal with two commands:

sudo chmod a + rw/dev/bus/usb/..../....

For example, the detected port name is 001/006, then the command is:

sudo chmod a + rw /dev/bus/usb/001/006

3. Done.
