Title: FT2232H Not Getting Detected over Windows Comm Port.
Post by: Siddharth Mishra on September 20, 2021, 02:08:50 PM

Hi there,

We are working on a project which uses FT2232H, The MCU is of Kinetis 20/22 family by NXP. While using Linux as the OS we can see the Comm Ports being created on the Terminal but the same setup is not working on Windows and gets listed in the Device Manager as (Device Descriptor Request Failed).

We have tried almost every solution available on the Internet from Installation of drivers to other files that can be of use to implement, also tried using another board with the FT2232H mounted on it but all in vain.

Also, If someone can suggest if we need to make any extra configurations to use UART in Asynchronous Mode alongwith FT2232H which as far as we know is pretty straightforward to implement. Help and Suggestions would be much appreciated.

Thanks !

Hello,

You should try uninstalling the drivers using our CDM uninstaller (https://ftdichip.com/utilities/#cdm-uninstaller) utility. Then install our windows driver:

However Device Descriptor Request Failed usually points to a hardware issue. Please contact your local support team and include your schematics:

Section 3.2.2 of the device datasheet (https://ftdichip.com/wp-content/uploads/2020/07/DS_FT2232H.pdf) describes the pin configuration to use the device asynchronous mode.
