Good news everyone, both issues…
- Only up to four x4 NVMe SSDs show up when the 90504 gets an x8 instead of x16 PCIe link
and
- The four “phantom” 87D0 PCIe devices in Windows Device Manager where drivers could not be installed (Code 28)
Have been fixed by a Broadcom firmware update you get when you annoy Delock’s Level 2 support a bit.
Hope that they’ll leave this link active:
