I didn't know that I should start the daemon with 'usbipd --device' after starting my emulation. I've tried it with 'usbip -d' and then bind my device with 'usbip bind -b BUSID'. But there wasn't listet a device by usbip with 'usbip list -l', so I didn't know what I have to bind. Mit freundlichen Grüßen Kind regards, i.A.
