Hi,

It seems that windows update has downloaded the incorrect driver for your device. If you manually update the driver, and point it to your SEGGER installation folder, it should be updated. My drivers are present in this directory: C:\Program Files (x86)\SEGGER\JLinkARM_V468\USBDriver\CDC

Best regards Håkon

Hi,

Did you try to right-click and update driver manually? Right click and choose "Update Driver Software" and browse to your SEGGER installation folder and it should detect your driver.
