A standard ftdiun2k.ini might contain:
If you are troubleshooting a computer where USB serial devices are not connecting, examining this .ini file can help determine if the correct Product ID is supported. "Gray market" FTDI chips (counterfeit chips often used in cheap Arduino clones) sometimes have slightly different PIDs, requiring manual modification of this .ini file to force the driver to recognize the fake chip—a common hack in the hobbyist electronics community. ftdiun2k.ini
Tells the uninstaller which specific hardware devices to target. A standard ftdiun2k
is a configuration file associated with FTDI Un2K , a tool used to interface with FTDI (Future Technology Devices International) USB-to-serial converter chips. It is most notably referenced in the context of ChipWhisperer (an open-source side-channel analysis tool) and certain hardware hacking setups. is a configuration file associated with FTDI Un2K
: You can run the uninstaller from a DOS command prompt by navigating to the system directory and using the FTDI Knowledgebase syntax: [Uninstaller name] [Full file path of INI file] . Key Technical Details
: The file relies heavily on the VID and PID matching what is defined in your hardware's .inf installation file.
