I have some strange behaviour of my STLINK V2 when I just plug it in the USB port and then open the STLINK Utility tool. When I then go to settings it finds the STLINK V2, but after about 5s the program seems to hang and the serial number disappears and it says "Old ST-LINK firmware / ST-LINK already used"
I use windows 10 and the most recent drivers for the STLink and the windows 10 drivers (STSW-LINK009). The STLink is just plugged in and the SWD interface is not connected to any device.
Has anyone an idea why this error occurs and how to fix it?
