Arduino Clone Driver for Linux

It is important if you are using UNO R3, Here is a list of Arduino clone driver Linux, click Driver Download.

There are some reported cases of serial communication failure when using the factory drivers in Linux. If you encounter this problem, you can try Installing patched drivers. Here are the steps (to run in the command line):

Plug and unplug your CH340 device from the USB port
Type dmesg to see what has happened
- The expected output (shows “ch341”) should have the following in the recent log:

[  xxx] ch341-uart ttyUSB0: ch341-uart converter now disconnected from ttyUSB0
[  xxx] ch341 3-2:1.0: device disconnected


Note: You will most likely need to obtain administrative privileges from your network or IT administrator in order to install these drivers.

Download the Patched Driver and unzip
cd goto the directory where the files saved
make clean
make
sudo make load
sudo rmmod ch341 to uninstall the broken driver
lsmod | grep ch34 to list modules currently installed
Plug and unplug your CH340 device again on the USB port
dmesg
Expected output (should show “ch34x” now):

[  xxx] ch34x ttyUSB0: ch34x converter now disconnected from ttyUSB0
[  xxx] ch34x 3-2:1.0: device disconnected

Depending on your root permissions, you may need to configure the serial port with the following two commands. Make sure to adjust the $username with respect to the user ID that is currently logged in.

sudo usermod -a -G dialout $username 
sudo chmod a+rw /dev/ttyUSB0

Depending on the CH340 enumerated on your computer, the /dev/ttyUSB0 may be different. Try using ls command as explained in the Driver Verification if you have issues configuring the serial port settings and adjusting the port as necessary.

Checking Driver Working for Linux

Please connect the device with the computer and type the following in the terminal

ls /dev/ttyUSB*

You should see this if the driver is ok
