There are only two reasons for lspci not to list the device:

(1) It is disabled in the BIOS.

(2) It is defective or not plugged in.

No. 1 is checked in the BIOS setup when booting. If nothing found there, and
re-seating the board does not help, then it is time for a new card.

If some device is not seen in lspci or lsusb, then it does not exist for the
operating system.
