Hi @sylow, thank you for the update and clarifying the situation. I understand you are already in contact with support directly trying to diagnose the issue but as you pointed out, the issue we have is to reproduce the problem ourselves which you mentioned is indeed very sporadic.
I assume you have already experimed with and without the hub, though I wonder if perhaps you tried disconnecting all other USB devices except the tracker? Might be interesting to see. In addition, did you look through both BIOS and Windows power settings? Please ensure that allowing the port to save power by deactivation is disabled in all cases!
Any report of similar behaviour with USB devices from your motherboard’s own support channel?
