FT232R Repair Manual

 

 

 

Many manufacturers’ boxes became victims of counterfeit FTDI chips, which are made in China and visually absolutely identical to the original chips.

Starting from FTDI driver’s version 2.08.14 there is a random connectivity issue for some users.
Drivers from version 2.10.00 started to "kill" all non-original ICs.
Fortunately, they do not destroy the EEPROM; drivers just replace PID with 0000, what makes it appear in Devices Manager as FT232R and, because of that, no other drivers can be installed.
2.12.00 drivers have been released recently and, apparently, they do not destroy PIDs.

Here is the manual how to repair your box PID if you became a victim…

  1. Uninstall current FTDI drivers
  2. Disable Windows Updater
  3. Download CDM Uninstaller
  4. Extract the file CDMUninstallerGUI.exe from the .zip folder and run the application, simply double click on the .exe file

 

 

  1. Type in Vendor ID - 0403 and Product ID - 6001
  2. Click on the "Add" button
  3. Type in Vendor ID - 0403 and Product ID - 0000 if you used modified PIDs
  4. Click on the "Remove Devices" button
  5. A pop-up message box will confirm successful removal from the system
