I review the doc, the cable may be the problem, but I have no idea how to test the output voltage and current.

For a Wrover-Kit, I solved by installing ftdichip drivers.

I saw it in https://www.youtube.com/watch?v=t-gMQDGB-9g
Maybe you should install another drivers to communicate the USB port to your board.
