bijkomende info : parallels ziet de stick wel (Devices/USB), maar als ik hem dan selecteer krijg ik de melding :
"USB device you are trying to connect to the virtual machine is being used by another process. Wait 5-10 seconds, then try to connect the device again. If this does not help, find the application that blocked up the device and disconnect it manually."
Wat kan hiervan de oorzaak zijn ?
