KVM2USB 3.0 No Video


#1

I am having the same issue as this customer with my KVM2USB 3.0

I am using:

  • Intel NUC PC (NUC8i5BEH), I’m using two identical setups, one is the Host, and one is the target being controlled
  • The full PC specs can be found on amazon by searching NUC8i5BEH
  • Ubuntu 18.04 completely up-to-date
  • KVM2USB 3.0 freshly opened from the box yesterday
  • KVM2USB 3.0 Firmware: 4.0.0.39896
  • lsusb shows device 2b77:3661 correctly enumerated
  • /dev/video0 and /dev/video1 devices are populated
  • Chrome and FireFox can stream the target PC’s HDMI connection from /dev/video1
  • opencv library can stream video and capture HDMI images just fine from /dev/video1
  • the Epiphan KVM2USB 3.0 Control Application starts up fine, and recognizes the KVM2USB device when it is plugged in.
  • The Control Application controls the mouse and keyboard just fine on the target PC.
  • The Control Application will not show HDMI video, but instead shows “Please connect your KVM2USB 3.0” …screen shot linked here

It appears quite simply that the Epiphan KVM2USB 3.0 Control Application has a bug that is preventing it from properly streaming the video deice /dev/video1 … all other features of the device / detection are working.

Any thoughts?

Could you send us an email, info@epiphan.com, with all these details? It will open a support ticket that we can assign to team members as needed to assist you.
This could take some back and forth to figure out.
