If you are running Linuxmin 19 use this instead.
I just got my first Arduino Uno board with a CNC shield and wanted to setup the development environment on my freshly installed Linuxmint 18.1 laptop to start playing with it.
Once I got the Arduino IDE installed and tried to upload some of the example sketches. I was greeted with the following errors.
Using Port : /dev/ttyUSB3 Using Programmer : arduino Overriding Baud Rate : 115200 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x00 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x00 ...
After Googling to get some idea of what is the problem. It seem that this clone is using the CH340G USB to serial chip instead of the FTDI chipset used on the Genuine board.
lsusb Bus 002 Device 005: ID 03f0:231d Hewlett-Packard Broadcom 2070 Bluetooth Combo Bus 002 Device 004: ID 1bcf:2805 Sunplus Innovation Technology Inc. Bus 002 Device 015: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter
The ch341 module that came with Linuxmint distribution was able to detect and load the module but uploading sketch using USB to serial communicating with this chipset is still a problem.
lsmod | grep ch34 ch341 20480 0 usbserial 40960 7 ch341,qcserial,usb_wwan
To resolve this. First remove the ch341 module and replace it with one build locally from source provided by the manufacturer.
sudo rmmod ch341 sudo mv /lib/modules/$(uname -r)/kernel/drivers/usb/serial/ch341.ko /lib/modules/$(uname -r)/kernel/drivers/usb/serial/ch341.ko~
Then download the driver source from here.
Unzip it and compile the kernel module locally and install it.
cd ~/CH341SER_LINUX sudo make sudo mv ch34x.ko /lib/modules/$(uname -r)/kernel/drivers/usb/serial sudo depmod -a
Unplug the board and reconnect and reconfirm the board selection is “Arduino/Genuino Uno” and the port is properly selected in Arduino IDE and the upload should work.
Hi, the tutorial was a great find! I’m using a chinese nano, not uno. Will the code still be same? I got some errors at the sudo make stage, and its failing. If it helps, here’s the stuff…

thanks, Dave:)
I am still running 4.10.0 kernel and I don’t get that error. Try to use the following command to find where wait_queue_t is.
find /usr/src -type f -name wait.h 2>/dev/null | xargs grep -l wait_queue_t
On my system, it is in:
/usr/src/linux-headers-4.8.0-53/include/linux/wait.h
/usr/src/linux-headers-4.10.0-35/include/linux/wait.h
/usr/src/linux-headers-4.10.0-37/include/linux/wait.h
If not use the following command to install the kernel headers.
sudo apt-get install linux-headers-$(uname -r)
In kernel 4.13.x you need a patch.
copy the contents below to a file and run the command patch ch34x.c

Thanks Ronaldo. I think the diff order is reversed. Also, it would be nice if the patched file support old and new kernels like so.
#if (LINUX_VERSION_CODE >= KERNEL_VERSION(4, 13, 0))
wait_queue_entry_t wait;

Thank you,
My mistake 🙂
I followed your suggestion of pre-processing. I updated the link with the new patch file.
Keep up the good work.
Hey I get the same error when trying to run ‘make’. I’m also affraid I don’t really understand how to apply your patch. I copied the text to a file, saved it, navigated to the direvtory I saved it in trough the terminal, and ran the command ‘patch ch34x.c’, but nothing happens. It just stays there doing nothing forever, and in the end I had to cancel the process as it seemingly would never finnish. Can you describe in detail how to apply the patch and install the drivers successfully? Would be a great help, thank you!
Looking at his ch34x_patch_kernel4.txt file header.

The following should work.
cd CH341SER_LINUX
patch -p1 ch34x_patch_kernel4.txt
