ST-Link USB communication error on Windows 10

I'm trying to use a ST-Link/V2 to program a STM32F4 device on my Lenovo E470 with the ST-Link Util. However, the ST-Link does not connect to any of my devices. I upgraded the ST-Link to the latest firmware and also upgraded the Util and the drivers to their latest versions. None of it had any influence. I've tried the same ST-Link and Device with the same version of driver on a Laptop of my co-worker and it works like a charm. I'm not using any hub to connect the ST-Link, I use the integrated ports of my laptop. I also tried a different a ST-Link with a different STM device with the same result.


As a last resort, I even reinstalled my OS to ensure that there is no USB driver that messes with the ST-Link. But it still does not work. I have no idea left how I can fix this problem. I hope someone can help me.
