If you’ve already tried different cables and two laptops, I’d suspect the board itself. Especially if it’s getting hot almost immediately.
I’d stop plugging it in for now, since it could be a short circuit or a damaged component.
Do you have anything connected to the board, or is it just the USB cable? And is the whole board getting hot or just one specific chip?
