using 2 UltraStudio Mini Recorder

Hello,

I'm having troubles using two Mini Recorders.
My actual setup needs to be 2 mini recorders and 1 shuttle intensity but I'm not even getting there.
I think the system can't make a difference between the two devices.
In OBS one device is ok, but when I connect a second one I get ghost input.
One Mini Recorder and the Shuttle is ok.
And once it has gone wrong all I get is a pink flickering screen
Help would be appreciated

Full system specs would help

I am having a similar problem.

I am using two UltraStudio Mini Recorders into my MBP.

I am running Keynote using an iPad HDMI cable to a splitter that sends the signal to a TV and to the Mini recorder
The other is from a Nikon D5300.

I am using a program called ManyCam to broadcast over Livestream. I can receive from one of the input sources but not both. Two Recorders show up as cameras in both ManyCam and the Setup Software, but only one input appears to be recognized by the device software.

When I am using the iPad the software show the output as 720p@59.64 and the camera shows nothing.
When I am using the Camera the software shows 1080p@59.94. Two cameras show up for a selection but selecting either one will only connect to the input that started working first.
