CC2531 USB not fully initialized

Hello All,

Need some help from the community. I bought this CC2531 USB Stick ( upload://6DE0JZaYBb0TclHPwV4s25Sv9En.png) )

Unfortunatly i can’t get it working.

I added the zigbee binding and installed it as a CC2531EMK Coordinator. Openhab says it’s online, gives the pan ID, Extended pan ID and the Network security key. But it is not showing Properties and it is impossible to add products like Hue lamps.

I already have read a lot in the community but cannot find a solution. I’m running Openhab 2.4 on a raspberry pi. I have changed the /etc/default/openhab2 (Java command line) and added a specifiek line to /etc/udev/rules.d/99-com.rules. Tried also other USB ports but the result is always the same. I have also a Zwave usb stick in one of the ports and that is working ok.

In the logs i found the next line: “UI
2019-09-27 12:14:58.109 [WARN ] [core.thing.internal.ThingManagerImpl] - Disposing handler for thing ‘zigbee:coordinator_cc2531:1beefa3f’ takes more than 5000ms”

Who recognizes this problem and is able to help?

Thanks in advance.
