Hello, I have the HP EliteDesk 800 35W G4 Desktop Mini PC and have a problem on bootup. Whenever I have my Mediasonic Probox (HDD power enclosure) USB device attached, it will freeze the PC on bootup, sometimes for a couple minutes, sometimes until I reboot it. I have no idea what's causing this issue as it doesn't happen on any other PC, not even my beelink mini pc.

 I know I can set the USB to not turn on until after boot, but I'm running Unraid of course.

 

When I have it plugged in when the PC turns on, it will freeze even if I'm just at the BIOS screen. And it will either unfreeze after 3 minutes or more likely just remain frozen until I turn it off manually. I have tried every option I can think of in the BIOS and nothing helps. I have replaced the USB cable, tried different ports, tried without any hard drives inside the enclosure.

Any recommendations as this is super annoying and I will have to return this PC if this cannot be accomplished. Thanks.
