Hi all!

I'm using a CY8CKIT-059 since few days with an USBUART block working without problems (show in PC terminal data from mcu).

But yesterday, I connected the USB cable and Windows 10 show me a driver error (device descriptor failure).

I programmed the same C8KIT with an USBUART example and it worked fine again...

But after, with my code again, doens't.

I'm using the default configuration of the USBUART block.

I don't  know why it broked.

I unistalled and re-installed PSoC Creator 4.2.

I select the driver from the folder of my project.

But doens't works.

Hello EmGa_3347101

You can try using the Microsoft Certified USBUART driver.

It can be obtained from the following link:

https://www.cypress.com/documentation/software-and-drivers/microsoft-certified-usb-uart-driver

Note: On Windows 10, you can use signed drivers only.

Please refer to the following thread regarding use of the driver: Re: Use of the Cypress Microsoft Certified USB UART Driver

Let me know if this works for you.

Regards

My project is working fine when using this driver.

Also can you attach the zip file for your complete project?
