DFU Util does not connect

I have put my Pyboard into dfu mode with connecting the pins. My device manager is showing up the stm32 in dfu mode, but dfu-util still can not connect.

Cannot open DFU device 0483:df11

You might not have the proper access rights. On Linux, try sudo, or/and look at that place: https://github.com/micropython/micropyt ... /README.md or https://github.com/micropython/micropyt ... are-Update
On Linux, you may add yourself (user name) to the dialout group.

On linux i had no problems, i also thought its a win10 problem.
When I used DFUse from ST it worked on win10

Thank you.
