No STLink Detected. CubeIDE 1.15 needs pc restart to program STM32

[Sujoy_B]

Hi, 

I am using an STM32F030C8T6 on a Bluepill PCB with STLink-V2 programmer. I have been successfully programming this board and others like it for a couple of years now. 

The issue is that on CubeIDE 1.15 on my laptop, the IDE refuses to program/ detect the ST-Link. ST-Link utility and cube programmer are able to detect the ST-Link easily as well as the STLinkUpgrade function within the CubeIDE can detect the ST-Link. 

It gets weirder as when I restart the PC, I can open the CubeIDE and program the STM32 once. If I try to enter the debug mode, the process gets interrupted midway but the Run command succeeds once. After that I get the message. "No ST-Link Detected. Please connect ST-Link and restart the debug session". The hardware works perfectly on two other PCs only my laptop is the issue. 

I have tried using other ST-Link devices on this laptop but there is no change. 
I've uninstalled and reinstalled CubeIde, CubeMX, ST-Link-server and ST-Link USB bridge but no use. 
I've tried updating libusb-1.0.dll but no luck there as well. 
I've tried uninstalling all STM32 windows driver packages and installing stsw-link009 - no change. 
I even tried installing st-link-servers Version 2-0-2, 2-1-0 and 2-1-1 again, no change. 

Snapshots of the successful and unsuccessful downloads are as below. Look forward to some guidance on this as I need the laptop for portable troubleshooting and diagnostics of my microcontroller.  

Regards, 

Sujoy

Please show us photos of your ST-LINK/V2, front and back. If possible, also a screenshot of the STM32CubeProgrammer when the ST-LINK is connected.

Update - It was a PC issue. After resetting windows 10 everything works.

Hello @geraldo ,

I recommend you start a new thread describing your issue with details, this will be easier for user forum to help and answer you.

So, please provide more details on your hardware, software environment such as: Which MCU, STM32CubeProgrammer version are you using? ..
