Conbee II problem, I don't see tty/ACM0

Hi, at the outset I’m sorry, my questions are probably stupid, but I’m a newbie at the beginning of the road. I have Home Assistant Blue edition (odroid n2 +) and Conbee II. I managed to set up Zigbee2MQTT and add Tuya TS0201, however after some time it stopped updating temperature and humidity. I started fumbling around and updated my Zigbee2MQTT. Unfortunately an error has occurred:
Zigbee2MQTT: error 2021-02-11 19:56:05: Error while starting zigbee-herdsman
Zigbee2MQTT: error 2021-02-11 19:56:05: Failed to start zigbee
Zigbee2MQTT: error 2021-02-11 19:56:05: Exiting …
Zigbee2MQTT: error 2021-02-11 19:56:05: Error: Error while opening serialport ‘Error: Error: No such file or directory, cannot open / dev / ttyACM0’
So I went into the configuration (hardware) to check the Conbee II port and noticed that the ports information is different than before. It was something like this at the beginning of info:
series:

  • / dev / ttyACM0
  • / dev / ttyS0
  • / dev / ttyS1
  • / dev / ttyS2
  • / dev / ttyS3

    Now the information in the hardware starts like this:
    devices:
    • name: ttyS0
      sysfs: / sys / devices / platform / serial8250 / tty / ttyS0
      dev_path: / dev / ttyS0
      subsystem: tty
      by_id: null
      attributes:
      DEVNAME: / dev / ttyS0
      DEVPATH: / devices / platform / serial8250 / tty / ttyS0
      MAJOR: ‘4’
      MINOR: ‘64’
      SUBSYSTEM: tty
    • name: ttyS1
      sysfs: / sys / devices / platform / serial8250 / tty / ttyS1
      dev_path: / dev / ttyS1
      subsystem: tty
      by_id: null
      attributes:
      DEVNAME: / dev / ttyS1
      DEVPATH: / devices / platform / serial8250 / tty / ttyS1
      MAJOR: ‘4’
      MINOR: ‘65’
      SUBSYSTEM: tty
      …etc.
      However, ttyACM0 is missing as evidenced by the Zigbee2MQTT logs. I have updated Conbee II to deCONZ_ConBeeII_0x26680700.bin.GCF. However, I still don’t see Conbee II. Meanwhile, I also updated the Core and Home Assistant OS. Below is the info about the current state:

Can you help me somehow?
