Problem with Zigbee2MQTT - getting Sonoff_Zigbee_3.0_USB_Dongle_Plus to work

Configuration Zigbee

I have big problems getting Zigbee2MQTT to work. My HA is up to date.
I am using the Sonoff_Zigbee_3.0_USB_Dongle_Plus.
After the initial setup, everything worked and I was able to set up devices.
After 2 days (Update HA ??), however, nothing worked, only error messages. I also changed the Sonoff_Zigbee USB stick, but the same problem.
The same problem was reported in various forums, but there was actually a working solution was not really available.
The error messages do not help me.
Is there anyone who is familiar with the problem and can understand and solve it?
Error messages:
error: zh:ember:uart:ash: Failed to init port with error Error: Error Resource temporarily unavailable Cannot lock port
error: z2m: Error while starting zigbee-herdsman
error: z2m: Failed to start zigbee-herdsman

Might be that something else is using the USB port.
You don’t happen to have ZHA enabled, do you?

I assume here that you already tried to reboot HAOS altogether (or even Shutdown-Remove power-Wait 10 sec-Re plug)

This one ? or the Sonoff_Zigbee_3.0_USB_Dongle_Plus_V2 ?

Hi,
it is Zigbee 3.0 USB Dongle Plus or Sonoff zigbee 3.0 ZBDongle E, with firmware 7.4.4

ZHA is disabled.

Maybe show your Zigbee2MQTT configuration.yaml

I use adapter: zstack with the same dongle. I am noobie but try it.:wink:

I had the exact same issue when setting up the same coordinator. I used “zstack” as the adapter and went on and disabled ZHA. I know you said ZHA was disabled but I had to into ZHA and disabled it again. The second time the coordinator started working as expected.
