I have looked thorugh my motherboard manual on this issue, but it doesn't mention anything specific about this, so I'm left a little confused.
My main PC has a MSI MPG Z390 Gaming Edge AC motherboard. I have 2 m.2 SSDs installed in it (one with Linux and one with Windows). I also have a third m.2 SSD installed in a USB adapter enclosure:

I believe the SSD in the USB enclosure is SATA-based.
If I plug the USB m.2 adapter into my PC while my PC is running, it recognizes the drive as expected, and all is good. However, if I leave the USB adapter plugged in (which I'd like to do), then when I reboot or power on my PC, the motherboard says one of the m.2 SSDs on the motherboard is not available (and it always seems to be the same one).
The motherboard manual does talk about the fact that some of the SATA ports will be unavailable when both m.2 slots are used, though it doesn't mention anything about USB devices affecting the m.2 slots on the motherboard. I've done some searching online, and it sounds like it may be due to bandwith sharing, and perhaps the motherboard is disabling that m.2 SSD on the motherboard for some reason, but I'm still not entirely sure if that's the case and if there's a BIOS setting I might need to change that would prevent the USB adapter from interfering with the m.2 SSD on the motherboard.
Has anyone seen a situation like this?
