FTDI 2.12.00 Notice - ROBOTIS USB2DYNAMIXEL, CM-530 and LN-101 - October 2014

We've recently been notified about a problem with the FTDI 2.12.00 driver update for windows. This update is effecting certain FTDI chips. These chips may be 'counterfeit' chips, or it may be a bug in the FTDI drivers. When the 2.12.00 driver is installed on an affected FTDI chip, the installation process erases the Product ID (or PID) on the FTDI chip. The PID should be '6001' but is being set to '0000'. So while the device works the first time it is plugged into the computer, it will stop working after it is unplugged/plugged in (regardless of what computer it is plugged into). This is a different problem from Last year's FTDI Driver problem

This problem currently effects all FTDI based products from ROBOTIS. The following products are included:

There is no evidence that the other FTDI based devices sold by Trossen Robotics have this problem. If you notice a problem, please let us know.

On Windows 7/8, it is possible to manually install older drivers and get the device to work. We've put together a Video showing you how to do this.

Manually Installing Drivers

For most recent ROBOTIS products, you can use the 2.10.00 drivers found on here. Scroll down to the 'No Longer Supported' table and look at the first row. Pick the 32-bit or 64-bit download depending on your system. (Put Control Panel\System and Security\System into your explorer window if you are not sure).

Some ROBOTIS products made at the end of 2013 and the beginning of 2014 will not work with the 2.10.00 driver (see more details here). For these users (or any users who want to be sure of a working driver) you will need to use a driver that is 2.08.28 or earlier. These drivers are not available on FTDI's website currently, but you can download an older copy of the driver 2.08.28 from our server here.

Unzip your drivers and put them in a folder on your desktop.

Open your Device Manager by searching for it on your system or going to the Start menu, right clicking on My Computer, and selecting 'Manage'. The Device Manager will be an option on the left navigation menu.

First you will need to install the USB Serial Converter Drivers

  • Find the 'FT232R USB UART' under Other Devices (you may need to click the triangle to expand the menu)
  • Right Click on 'FT232R USB UART'and select 'Update Driver Software' *
  • Click 'Browse My Computer for Driver Software'
  • Click 'Let me Pick From a List'
  • Select 'Show All Devices'
  • Click 'Next'
  • Click 'Have Disk'
  • Navigate to the folder on your desktop that you unzipped the drivers to
  • Click 'ftdibus'
  • Click 'OK'
  • Select 'USB Serial Converter'
  • Click 'Next'
  • There will be a warning - Click 'Yes'
  • Click 'Close'

Now you will need to install the USB Serial Port Drivers. The directions are similar to the first ones, but not identical

  • Find the 'USB Serial Port' under Other Devices (you may need to click the triangle to expand the menu)
  • Right Click on ''USB Serial Port' and select 'Update Driver Software' *
  • Click 'Browse My Computer for Driver Software'
  • Click 'Let me Pick From a List'
  • Select 'Show All Devices'
  • Click 'Next'
  • Click 'Have Disk'
  • Navigate to the folder on your desktop that you unzipped the drivers to
  • Click 'ftdiport'
  • Click 'OK'
  • Select 'USB Serial Port' from the bottom of the list
  • Click 'Next'
  • There will be a warning - Click 'Yes'
  • Click 'Close'

*If you do not see the 'Update Driver Software' option from the menu, windows is attempting to install drivers on its own. Either cancel this, or wait for Windows to finish its attempt to install the drivers.

Now restart your computer, and you should be able to use your device without problem.

Advanced Users - Restoring Product ID

Is is possible to restore the Product ID on your FTDI chip using the FT_PROG utility. We only recommend this for advanced users who specifically need the Product ID restored. Even after the PID is restored, the 2.12.00 driver can still remove the PID number, and you will need to repeat all the previous steps. For more information on how to use FT_PROG see this video at 6:00

Notes On Windows XP

Windows XP may have a harder time getting the device setup. You will need a Windows 7/8 computer to recover the Product ID on your device, then uninstall the 2.12.00 drivers from your XP computer. Finally install 2.08.28 or 2.10.00 drivers onto the XP machine for the FTDI device. We recommend you be unplugged from the internet while you install the device.
