Conbee II not detected after host reboot

[rosek20]

Hi.

I have home assistant supervised installed on intel nuc. The conbee ii is configured and all is working fine. The only problem I have is when I reboot my home assistant (host reboot) most of the time the conbee II is not detected by home assistant os and I have to restart home assistant few times to get it back.

I am using device: /dev/ttyACM0 in configuration for deconz addon. (tried all different configurations but when conbee is not detected by the os this is not helping)
When conbee ii is not detected after reboot I can’t see it in devices available in hardware of a host (no usb devices detected).
Conbee ii is connected through usb2 extension to intel nuc. I have tried every usb port, tried using it without usb extension etc.. but no luck.
Can you pls help me with this problem. Is it possible that conbee ii might be faulty?
