Ebus2 port already in use

Hi all,
I’m trying to get the [[eBUS 2.0] New binding - Release Candidate 7b] up and running.
I’ve attached a Serial / USB - Ebus adapter attached (this one https://wiki.fhem.de/wiki/EBUS with an FTDI adapter)

I got the error
[ERROR] [ion.EBusSerialNRJavaSerialConnection] - Serial port /dev/ttyUSB1 is already in use

with ebusd it is working properly
ebusd -d /dev/ttyUSB1 --enablehex --scanconfig= -f -p 8888

any Idea?

You shut ebusd down, so it would release the port?

ebusd deamon is not running
