Problem with sedu controller

Hi,

I have a raspberry pi 4 with Hyperion image and I try to run the LEDs with my old sedu controller. I can configure it, as well as my USB-3 HDMI grabber. The grabbing sems to work, but there is no output on the LEDs. I also tried to run the LEDs using the Hyperion controller app without success.

Any idea wht could cause this? The only error I saw is "Lock/Unlock Handler - Session bus is not connected". How can I debug this in detail?

Actually I am not convinved that the error from the lock is really pointing to the problem.

I did some tests again today, and the only things that is not working is the control of the LEDs via Sedu V2, which works on the enigma2 device (but thre I do have a major issue with the grabber not working properly).

The grabber works fine according to the control view in the hyperion web page, it also seems to calculate the colors for the LEDs correctly, but the hardweare stays dark

Is there really no one else using Sedu V2 to control the LEDs anymore?

The colors work fine in the preview in Hyperion. Ther sedu V2 is detected correctly and the setup should be fine. But the LEDs stay off and I do not see any error besides the "Lock/Unlock Handler - Session bus is not connected" that I cannot get rid of. But actually I do not know if this error is really related to the problem.

What can I do to debug this better? And what can I post here to get some support/ideas from you guys?

Yes the USB capture is enabled:

I will create the debug log, now, and post it here

This is the preview in Hyperion:

Sometimes to obvious is not so clearly visible. I missed that with Custom I could enter my value, so I chose th closest one, which apparently did not work. Thanks a lot, it works now with 500000 as bandwidth value.

Of course, now more questions come up: The blue value is too dominant and with the calibaration tool I was not yet able to get a real and good white. Do you have some tips by chance before I will search the forum?
