If your cheap Arduino clone stopped working recently you’re probably experiencing FTDIgate 2.0.
I won’t go in deep details here because I already spent too many hours solving the issue but here’s what’s happened in a nutshell: a new FTDI driver was force installed through Windows Update which renders the counterfeit chips useless again. This time the update is much more aggressive and a little bit harder to remove.
So if you have an Arduino clone that mysteriously stopped working (unable to upload new sketches) in January here’s what you can do:
- First connect your device via USB and open up Device Manager.
- Right click your device (Mine is USB Serial Port (COM5)) and click Properties -> Driver
- Take a look at Driver Date. If it is a new version like 1/6/2016 than you are affected by FTDIgate 2.0. Continue reading…
- Download and run CDMUninstaller from FTDI Utilities, click “Add” to add the device to the list and click “Remove Devices”. This removes every single instance of the FTDI drivers.
- Right click on START menu -> System -> Advanced System Settings -> Hardware tab -> Device Installation Settings
- Check “No” and Save Changes
- Open up the Registry Editor (regedit in command window). navigate to this setting:
- Change the value of SearchOrderConfig to “0”.
- Now restart your computer.
- After restarting, open up Windows Update and you should see an available update:
- Now that is something we really want to avoid. Download the “Show or hide updates” tool from Microsoft and run it.
- Click Next.
- It will show available Updates which you can hide forever. Select the two FTDI entries and click Next.
- Click Close.
- Now install manually an old version of the FTDI driver. (Right click on the device in Device Manager -> Update driver software -> Browse -> …)
- Open up the Registry editor again and switch back the value to “1”, so other drivers can update normally.
That’s it as far as I remember. I did many-many trials and errors and just typed everything in a rush, so there might be mistakes above. If you have any questions or comments please don’t hesitate to share them.
