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.
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.
For anyone else who runs into this - on newer kernels the device to read from is /dev/video0, but the software tries to read from /dev/video1. It’s ugly, but you can do:
rm /dev/video1
ln -s /dev/video0 /dev/vide1
to get it working. I have a ticket in requesting this to be configurable.
Same issue here on Ubuntu 19.10 and I confirm this hack works for me too. It probably won’t survive a reboot, but thank god this mean the device work and a fix can be worked out.
A year ago, I prepared an updated version of the control app, but for some reasons it was not published. At least, issues with incorrect device was solved:
Hello,
I have the separate problem. When I’m trying to open the KVM app in fullscreen mode and screen resolution of the target PC is 1920x1080 (similar to my host PC), the KVM app suddenly closes. If I’m trying to do this with different resolution of the target and host PC, like 1920x1200 on target and 1920x1080 on host, everything is working fine (with black margins).
Maybe this issue was fixed in some internal builds too?
My host PC configuration is:
KVM app 0.99.27
Windows10|
Intel® Core™ i3-7020U CPU @ 2.30GHz 2.30 GHz|
4,00 GB
Win10 64 bit LTSC
