STM Virtual COM Port not working in windows 11

[Neeraj]

Dear ST Community,

I'm using Windows 11 on my PC but the device manager doesn't detect the STM32 USB VCP. Please help me fix this issue.

best regards

Hi,

what happens , when you connect to PC/USB ? 

If nothing at all, try other USB cable (with data lines), maybe you have a charger cable now ...

I changed the cable, but the issue remains the same.

I am using CDC Lib for sending messages.

Does anything happen at all on the PC when you plug in? eg, does it see any "unknown" device? or report any error?

Presumably, your embedded code should also detect when it's plugged in - is that happening?

[Neeraj]

Nothing happening at the PC End

[Andrew Neil]

So what about the STM32 end?

What debugging have you done to see what's happening there?

i have the exact issue but when i connect the usb it says usb device not recognized on my pc end 

[Andrew Neil]

So that's not the exact issue, then - is it?

In @Neeraj's case, nothing at all happens on the PC;

In your case, something does happen - so yours is a different issue.
