Hi, sorry for your connection issue. A few questions:
What is your connection method: direct ethernet, ethernet from your router, or WiFi using the USB dongle? What H9k firmware version and Emote version are you using?
If you are using the WiFi dongle, you can try unplugging it from the H9k's USB port and plugging it back in to reset the connection. The best way to troubleshoot if there is a connection issue would be to see if a direct ethernet connection from the computer to the H9k allows you to connect to Emote.
Emote does not connect via USB so your connection issue is independent of it showing up as a USB device on your computer.
Just to clarify, your H9k can connect to Emote on your laptop (MacBook? What OS?) but not the Mac Pro when using the same connection method?
Please let me know and I can help you troubleshoot your issue further.
