STM32H735G-DK STLINK no STLINK USB enumeration.

[BKrak.1]

Hi,

I just bought STM32H735G-DK and USB is not working out of the box.

I have put jumper on STLK but device is not getting detected on PC(LD6 red/green dim lit).

There are no new devices in device manager when plugged in.

Board is running original program just fine, power on and all.

Am I missing something? Is there something I can do?

Best regards

Oh, ok It sounded differently in my head.

I didn't buy them they were laying around in my house from power bank charging to cell phone charging cables.

I measured one and didn't get signals through.

The one from old Samsung phone worked.

I cut one and it only has 2 wires for power in it. First time I saw that.

That really took me back to school:).

Next time test the cable with some known working board.

Yes I should do that.

I was convinced that cables were OK.

Big thanks to both again!
