I've attached the output of "lspci -t".

0d:00.0 Non-Volatile memory controller: Sandisk Corp WD PC SN810 / Black SN850 
NVMe SSD (rev 01)
00:14.0 USB controller: Intel Corporation C610/X99 series chipset USB xHCI 
Host Controller (rev 05)
01:00.4 USB controller: Hewlett-Packard Company Integrated Lights-Out Standard 
Virtual USB Controller (rev 03)

The above seems to be the relevant lines from "lspci".  How do I determine how 
close these things are to each other in topology?
