Hi,
I bought eight of these from Aliexpress. The red power led is on after connecting the PCIe and the GND-5V-5V cable, but my NVMe disk is not detected. I use a new Kingston NV2 PCIe 4.0 NVMe M.2 500GB, which is normally compatible.
I tried adding in /boot/firmware/config.txt either one or the other and reboot:
dtparam=pciex1
dtparam=nvme
Nothing worked. Can you please help?
Thank you!
Alex
