It looks like your adapter is not recognized as a PCIe device. When you run lspci, you should see something like the following:
3a:00.0 PCI bridge: ASMedia Technology Inc. Device 2463
3b:00.0 PCI bridge: ASMedia Technology Inc. Device 2463
3c:00.0 Co-processor: Hailo Technologies Ltd. Hailo-8 AI Processor (rev 01)
As written above, the chip in the adapter is from ASMedia.
If you have an M.2 PCIe NVME SSD you can try the following steps.
- Replace the Hailo device with the SSD and plug it into the port.
- Run
lspciagain. You should get something like this:
02:00.0 PCI bridge: ASMedia Technology Inc. Device 2463
03:00.0 PCI bridge: ASMedia Technology Inc. Device 2463
04:00.0 Non-Volatile memory controller: Sandisk Corp Device 5042 (rev 01)
If you do not see this, run lsusb. If you get something like the following, your port is setup for USB, not PCIe.
Bus 003 Device 024: ID 174c:2463 ASMedia Technology Inc. Ugreen Storage Device
You will only get one or the other because the SSD can support both PCIe and USB, depending on the port it is connected to. I have tested this on different machines with both types of ports.
Additionally, check the BIOS to see if there are settings for the ports.
Thanks to Amazon’s return policy, you can also try an adapter from Orico. See the post here for additional adapters I have tested:
