Sorry for the late reply.
The Leap Motion device is connected corectly. I think the problem is with the array. Please check the attached screenshot as i run the device.
The software can't recognize my array. And my serial number is UHDK5-000003AC. What should I do to solve this problem? By the way, my palm can't feel the virtual haptics generated by ultrasonic at this time. Even the array does not work properly to produce ultrasonic waves.
Thank you very much for your help. And I hope to hear from you soon.
