Zigbee Stick CC2531 will not go online, Bridge offine

Hello Community,
i have bought a Zigbee USB Stick and plug it in on my intel nuc. So with dmesg i found it and the port type tty/ACM0.

So i make some changes on my system like this.

sudo adduser openhab dialout
sudo adduser openhab tty


So in my things file i add this stick like this on the wiki page.

Thing zigbee:coordinator_cc2531:bbd6a1f2 "Zigbee USB Stick" [zigbee_port="/dev/ttyACM0", zigbee_baud="38400"]

So but in paper ui the stick is offline. So whats my problem, where i make errors and how i bring this stick online ?

Here some log entrys


No one an idea, where my mistake is ? Why did that working for me ? Or did you need some more information ?
