I have changed PID and VID of my FTDI board for arduino program because i wanted to rename the com port name. The ic is FT232R a USB to serial UART interface IC. I have store new vid and pid to EEPROM. Now It is showing in unknown devices. I am not able to update driver of it. I have followed this article http://forum.arduino.cc/index.php?topic=6929.0.

Can anyone tell how to make cutmoize driver for it. Any suggestions will be very helpful.

  • Most likely you want to edit the .inf file to add new VID/PID options. – Majenko May 27 '16 at 11:36

  • You may need to go through the convoluted "Update Driver" route in the device manager. It's not a nice method. You may need to (somehow) uninstall the old driver so that it will pick up the new one. – Majenko May 27 '16 at 14:43
  • @Majenko Windows is saying the new driver is corrupted. – Aman Srivastav May 27 '16 at 14:46
  • I have installed the customize driver to windows but forcefully because to driver signature issue. How to get it solve. – Aman Srivastav May 30 '16 at 12:27
