CubeProgrammer reports RDP over native USB

[tguly.1]

When plugging in a device in DFU mode to a native USB port of the notebook cubeprogrammer reports:

When using it over USB HUB or other port the Cubeprogrammer works fine (we never activated RDP).

USBDeview shows no difference in the installed drivers. Happens on various machines/pcs/notebooks.

Hello @tguly.1​,

Could you please provide further details on the issue you're facing ? (e.g. a verbose 3 log, STM32CubeProgrammer version, specs and brand of the used machines, are you using a custom or built in STM32 bootloader...).

Thanks,

Aziz

faulty case

correct case

[tguly.1]

The only difference between these 2 cases is that for the faulty one I used the onboard USB controller of the motherboard. The OK case were produced by attaching the DFU device to a PCIe USB extension card.

We noticed that when using the "Intel(R) USB 3.1 eXtensible Host Controller - 1.10 (Microsoft)" controller with version 1.10 it works. With version 1.20 it results in fault.

When a USB hub is placed between the 1.20 version of the controller and the device it also works.

so

1.10-----DFU [OK]

1.20-----DFU [NOT OK]

1.20-----USB_HUB-----DFU [OK]

Hello @tguly.1​,

Thank you for your detailed answer and analysis !

I have managed to reproduce the issue on my side and it seems that it's related to the driver version. I also tested using DfuSe tool and I have seen the same behavior (with Intel(R) USB 3.1 eXtensible Host Controller - 1.20), so most probably this is not tool related.

I have submitted an internal ticket to bootloader team. Hopefully they will manage to debug the situation further.

Internal ticket number: 147651 (This is an internal tracking number and is not accessible or usable by customers)

I will get back to you as soon as I have any updates.
