I'm new to using the ST-LINK, and I'm trying to isolate a connection problem, by checking if the ST-Link itself is working well with my computer.

I connected the ST-LINK V2 by itself to a Windows 10 laptop. Nothing is connected to it, bar the USB cable connecting it to the computer. It's being recognized as STM32 STLink in the device manager. When I open STM32 LS-LINK Utility, I press connect, and get:

STLink USB communication error

When I open ST-LING -->Firmware update, and press Device Connect, I get:

Communication error with ST-Link. Try to start it.

Which is unclear, considering it has no buttons

Is this sane?

Fixed it. There was one USB port that worked.
