@SimonF - indeed it looks like same issue as I'm facing. Thanks for that. So what's left for me is to wait till Unraid will include that.

Thanks everyone for an answers. @BRiT - it seems that disconnecting is the issue here, but still don't know why it is getting disconnected @SimonF - yes, have it as well. But it is still manual work every few days, where my expectation is it's running 24/7 without my attention. @bastl - so as I understand up to now, issue is rather with my hardware and kind of physical connections than with unraid itself? I will try to check that and come back later PS. my HW is "Lenovo M710q USFF", which has not space inside (I believe) to attach another card

But once device ID starts being changed continuously, device (conbee2) get unaccessible inside VM, and only stoping and starting VM solves the problem .. at least for some time (few days).

@bastl - thanks for your reply, but I still don't understand what should I do. Adding extra pcie is not a case for me as don't have a space in my tiny PC case. But what is worrying me and don't think it is normal, is that conbee device ID is changing sometimes continuously without any action/trigger (like e.g. vm restart because of update).
