I have the following Ft232rl Ftdi Usb to Ttl Serial Adapter Module:

 

Ft232rl Ftdi Usb to Ttl Serial Adapter Module

I thought I had the DTR wired to ground (by mistake), causing the unit to stop working. Would wiring the DTR fry the Ft232rl Ftdi Usb to Ttl Serial Adapter Module? At first I thought yes. I confirmed that the unit is not working on my windows 8.1 machine, but windows does get a device ID:

 


 USB\VID_0403&PID_0000\A9UXT3FV

 

Some googling I found that there was a Windows Update to block Chinesse knock offs. I found this https://www.youtube.com/watch?v=... tutorial online which help me resolve this issue. I am wondering if anyone else had this problem?

 

I also confirmed that my MAC does recognize it anymore. Perhaps its block there too? I thought I fried 3 of these last night sad, but it looks like I didn't. Any thoughts or guidance is greatly appreciated.

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

Thanks - I was able to manually add the drivers on my Windows machine and all is working. I Still haven't tried to resolve on my Mac and Linux boxes via this solution http://www.eevblog.com/forum/rev...

So from what I have been reading online is that the Windows update bricks the FT232 chip by setting the pid = 0000. You can manually install the windows drivers with the you tube tutorial I posted in the first thread. This allows you to use the device on that machine, but since the chip is bricked I can't use on my mac or linux box. The solution is to use the mProg.3.5 Programmer on http://www.ftdichip.com/Support/... to un-brick the chip. The only problem is when you plug the chip back into the windows box, its bricked again. So my temporary solution is to do the following:

 

  1. Only buy Certified FTDI chips laugh
  2. For my existing FTDI chips, designate some for my Windows and some for my mac
