Title: Windows FTDI 2.14.1.3 driver
Post by: FHB on March 25, 2022, 02:17:43 PM
Hello,

We are using the FTD2XX C++ library to communicate with FT230 and FT245 devices.
We usually install the 2.12.28 driver with our software, but found the 2.12.36 to also work.

One of our client was having trouble, and when investigating we found that a version 2.14.1.3 was installed.
It seems to have been installed with a Windows update from December 2021.

When debugging the 2.14.1.3 driver, trying to open a device with the `FT_Open` returned the error code 3 `FT_DEVICE_NOT_OPENED`, and `FT_ListDevices` returned devices with empty informations.

Here are our questions:
1. Why is the 2.14.1.3 driver not listed in the D2XX drivers page?
2. Is there a solution to the 2.14.1.3 driver not working with our system, other than downgrading the driver from Device Manager?

Thank you in advance,
Felix

Hello,

driver version 2.14.1.3 was a development driver that was not for general release. it has the same core functionality as the latest driver on the website.

i recommend that you uninstall 2.14.1.3 using our CDM uninstaller and then download the latest driver from the website.

when using the CDM uninstaller run it with the VID (0x0403) only.

Best Regards
