I have one of those propietary NGFF M2 SSDs found in older Macbooks. I bought a converter which is supposed to convert it to a standard NVMe. When I plug it in my Linux box only sees it as a SCSI device. It doesn't show in lsblk and I can't dd anything in and out of it.
This is dmesg after I plug it in:

This is what I got going on:

And that ^ is plugged into an NVMe to USB converter:

Haha, looks very rigged. No wonder it doesn't work! But I did try the NGFF to NVMe converter directly into a PCIe NVMe card and I'm getting a similar result:

UPDATE:
I tried another Mac NGFF SSD and a different brand NGFF to NVMe converter and I'm getting the same exact dmesg
