Holy f#*$ing Shit! It works! It works! It works!
I deinstalled all old Tobii software, restarted the system, installed the tobii software again, restarted the system, replaced the “libusb”, restarted again – nothing works… pluged out the usb-cable , reconnected the usb-cable and the calibration starts.
WOW WOW WOW!
Thanks to the whole supporting team! Really great to see, how fast you answer an how long you keep the contact! Thanks a lot!
