New eBUS Adapter 3 USB and

[gperdach]

Hi,
I installed new eBUS Adapter 3 and connected it via USB to my Raspberry Pi 3 Model B Rev 1.2 with debian 10.
I am always getting a "read timeout" on scanning the master/slaves. Before switching to eBUS Adapter 3, I used E-Service GmbH: eBUS Koppler Ethernet - devices were recognized normally.

I got following output on startup:

Do you have any idea, what is wrong?

please try with "--latency=20" as additional start parameter to ebusd
