My guess would be that whatever user this is running as does not have permission to access /dev/ttyusb0 (your USB devices). Here is a link that should give you something to look into: Zigbee2MQTT fails to start | Zigbee2MQTT

You are going to need to figure out what linux file path your dongle is visible at.

You do not state what platform and HA install type you are running your Home Assistant on.

If you are using a standard linux machine to run Home Assistant, or if you can get to the command line, you will want to do a directory command similar to the following to find your dongle. It is recommend to put your dongle file path in the zigbee2mqtt configuration.yaml file this method, rather than the /dev/ttyXXX way. Good hunting!

 ls -lR /dev/serial/by-id/
/dev/serial/by-id/:
total 0
lrwxrwxrwx 1 root root 13 Dec 30 16:40 usb-ITead_Sonoff_Zigbee_3.0_USB_Dongle_Plus_d8cdec347b29ec118a72757840c9ce8d-if00-port0 -> ../../ttyUSB0

in this example, the path to your dongle to enter into your configuration.yaml would be:

/dev/serial/by-id/usb-ITead_Sonoff_Zigbee_3.0_USB_Dongle_Plus_d8cdec347b29ec118a72757840c9ce8d-if00-port0

configuration.yaml section would look like :

frontend: true
mqtt:
  base_topic: zigbee2mqtt
  server: mqtt://192.168.56.13:1883
serial:
  port: >-
    /dev/serial/by-id/usb-ITead_Sonoff_Zigbee_3.0_USB_Dongle_Plus_d8cdec347b29ec118a72757840c9ce8d-if00-port0

Also make sure nothing else is connected to it, like for example the ZHA integration

Zigbee Coordinator is a serial adapter and it can only ever have a single connection.
