Beware: FTDI driver update will brick *fake* FTDI USB to serial converters

Charly86

Hi guys,

Just to let you know that the new FTDI driver has changed the way on how it can make us crazy again. Now it does not change PUID anymore, it just send a dummy string over serial.

I just spent too much time trying to get my modbus (chinese USB/RS485 with fake FTDI chip) working until I saw master sent the good char and slave receive "NON GENUINE", so it's harder to detect because all seems to work, but transmission has been changed by this f**** string and you receive other than you send and vice versa

Anyway, thank's FTDI's guys making our life complicated, and guess what, since I can't know in advance if device I buy has Genuine or not FTDI chip, my only option is to go to ch340, cp2306 or other...

well, good that I'm using Linux then, no such problems, as broken FTDI drivers :)

@tbowmo even better: Linux has a fix for the "broken" devices:

Thanks for reporting.. Didn't FTDI learn anything from the last mistake they did?

I am facing the same problem. I purchased my FTDI FT232RL from http://www.ebay.com/itm/-/111864322684

When I plugged it into my Windows 7 PC, it pops up this error...

In my device manager, I sees Unknown Device under Universal Serial Bus Controllers...

I have tried update the drivers using various versions such as...

All still give me the same error.

When I use a tool called USBView downloaded from http://www.ftdichip.com/Support/Utilities.htm#MicrosoftUSBView , it shows me...

Both idVendor and idProduct are 0x0000

Then I use MProg 3.5 downloaded from http://www.ftdichip.com/Support/Utilities.htm#MProg . After I press scan, it says...

Number Of Blank Devices = 0
Number Of Programmed Devices = 0

I have wasted a lot of time to get this working. I really don't want to replace my unit with the same thing as I afraid the same problem will happen again. I am wondering is there any other ways to upload the sketches to my Arduino Pro Mini?

If you have an Uno around your can use that for programming the ProMini.

You can use another Arduino (preferably one with built-in USB port, otherwise you will end up in catch-22). https://www.arduino.cc/en/Tutorial/ArduinoISP It has the added benefit that you can set fuses. You will be unable to use the serial port for debugging though.

I would just order from some place(s) else and hope to get a working adapter. I have ordered 5 and all of them work on my Win7 machine. You could also try the CH340 chip.

What I've done is to buy some of these pretty USB/Serial adapters, from tindie
https://www.tindie.com/products/ddebeer/usb-to-serial--uart-5v-or-33v-695-/
with 5V/3V3 on board switch, CH341 chipset, and 3V3 on board regulators for ESP8266 for example

Time you win, problem went away, and bye bye FTDI problems, seriously Worth it !!!

@masterkenobi from what I've heard, FTDI has reverted their software so it won't brick fake chips anymore. If this is true, it is very unlikely you're hit by this issue, unless your windows 7 PC was very behind on updates and you just happen to have the flaked driver.
I think it's much more likely you received a board with a defect, or even with a dummy FTDI chip.

Thank you very much! Now time to dig out my old spare Uno.

Thanks. May I know where did you buy them from? CH340 chip? Also from FTDI?

Thanks. But after add shipping, I feel it is not worth it compare to get a new Uno from the nearest electronic shop.

My Windows is auto updating itself and I don't think it is a flaked driver cause I have installed multiple versions of the drivers.

The point is that once you have the driver installed that will brick your fake FTDI adapter, and you then connect the fake adapter, the driver will immediately destroy the adapter.
Once this has happened, the adapter can no longer be used, with any driver. Switching drivers will not make a difference.

These all have worked well for me (but I might have been lucky):

Yes it's more expensive, but compared to the days I spent thinking I had a problem with my code and it was just a driver change that broke everything, trust me, in my case, worth it (and it was 2nd time of driver problem, so we'll have again and again in the future). By the way, on the link I posted, they have on board regulator and 5V/3V3 switch that make them suitable for powering ESP modules that the other can't do seriously ;-) Love them

Anyway, any chinese FTDI chip claiming FTDI original are fake, trust me I've got 10, all fakes and I even built my own with chinese FT232 chip bought on ebay, and guess what, they're also fake.

But any other cheap chip other than FTDI will works ;-)

This one should do the trick

It's weekend and I finally have the time to give this another chance and guess what? It works! I manage to upload the sketch to my Pro Mini and successfully created my first ever MySensors sensor! Thank you so much for that!
