I will do that, thanks in advance!

The hub was even not working on my bench with only one mixer connected. Even without anything connected.
I was inspecting and measuring the things I could do without the schematics and didn't find anything wrong. Than I puched one spot on the pcb to detect soldering problems, the led "clock" went immediately from red to green.
Now it is working for 3 hours. So now I have to find the bad contact. could be pretty impossible on a digital smd unit without schematics.

Keep you informed
If you think you might have soldering issues on a board, you can reflow the solder using a heat gun. I fixed my friend's laptop this way. It sounds hokey, but it works. No need for schematics.
