USB FS driver detection with Windows PC.

I am trying to make USB FS driver detection by host PC.

I made some changes to the driver as per the youtube link:

https://www.youtube.com/watch?v=Jpul3w10tOU&t=1175s

 

The application is sending 'Hello World' string every second to the Serial port.

The problem is I am not able to detect the USB driver on the host Windows 7 PC.

I installed STM32 Virtual com port driver (my device is stm32f411rct6).

It is showing 'Unknown device' or 'USB device not recognized' 

When I see the properties of the device, it says 'Code 43'.

Please update me about this.

Thanks,

Hello

Ch.Pradeep

,

T

ry to increase heap and stack sizes and you can compare your generated code withthe

CDC application provided within STM32CubeF4 firmware package

to deduce what is going wrong in your case.

P

lease keep me informed on yourprogress.

Regards

Imen

I'm going to guess device manager shows 2 devices?

Next guess would be you probably need to finish the last couple of steps of the setup / drive install from the STM directory where the driver installation files were COPIED (but not INSTALLED) .. It's easily confusing.

Initially I want to communicate with Windows PC, but my goal is to connect to an Android tablet.

I did not find any stm32 virtual com port in Google Play, Do you have it ?

Imen,

Yes, I increased stack and heap sizes, I am going to try it in nucleo board once.

Shingadaddy,

I double clicked on 64-bit Windows 7 drive file which is my machine configuration. I did that as it was suggested in Readme file.

Thanks,
