Hello,
I am trying to connect to the STM32F072C8T6 microcontroller via USB in the STM32CubeProgrammer, however I am getting:
"Device is under read out protection ! If you want to disable RDP please reconnect with Read Unprotect enabled"
So, when I check the Read Unprotect (MCU) checkbox, I get:
"Please Power off Power on your device."
After turning the power off/on, I see the same messages. I cannot connect to the MCU via USB in the STM32CubeProgrammer.
I have tried different versions of STM32CubeProgrammer:
Moreover I tried on second computer with Windows 11 and I have the same issue.
I'm trying to connect my custom board, but I also checked another hardware board (BluePill ) with the same STM32F072C8T6 MCU and it doesn't work either.
Interestingly, using the DFU-util v0.8 program I can connect to the MCU and successfully read/write memory:
Solved! Go to Solution.

Hello @Draxter
Regarding this issue, we are aware of it and it's currently under investigation.
Internal ticket number: 171192 (This is an internal tracking number and is not accessible or usable by customers).
As a workaround, we suggest connecting your MCU using a HUB instead of plugging it directly into the PC.
Thanks,
Amine.

@Amine_Jridi thank you. Connecting the board to an external USB HUB solves the problem.
We are unable to understand what is root cause. Why use a USB HUB instead of a direct connection to a computer?
