Device not showing lspci - what then ?

Ok, let me change the title, because i am really confused, and i think this is a fairly generic question:

If i have a PCI device (PCIe card or the like), and it does not show up in "lspi", and there is not even an unknown PCI card showing up. What can i do then to troubleshoot why it's not even found ?

Eg: even if i do not have a driver for the PCI device itself in the kernel, i should at least see the device or an unknown device listed in lspci, right ?

In my case, i have a Transcend TS-PDC3 PCIe card with SATA and USB 3.0, and the SATA part of the card is working with disks connected, but i can not see anything of the USB 3.0 part on the card. And i think i had it working in before, but i can't find proof of it anymore.

% lspci
... skipping bus 0/1 which seem to be a lot of onboard and PCI slot devices, the following is for PCIe:
02:00.0 Multimedia controller: Digital Devices GmbH Octopus DVB Adapter (yes, PCIe card).
03:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 210] (rev a2) (yes, PCIe card)
03:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1) (second device on the GeForce 210 card).
04:00.0 PCI bridge: PLX Technology, Inc. Device 8603 (rev aa) (no idea)
05:01.0 PCI bridge: PLX Technology, Inc. Device 8603 (rev aa) (no idea)
05:02.0 PCI bridge: PLX Technology, Inc. Device 8603 (rev aa) (no idea)
06:00.0 SATA controller: ASMedia Technology Inc. ASM1062 Serial ATA Controller (rev 01)
( the SATA part of the RS-PDC3 card).

How can i best troubleshoot this ?

It probably will not help, but try lshw.

Or try lsusb.
If you get command not found emerge usbutils.

Hi

I found this article on how the card should be announced on pci:
http://ubuntuforums.org/showthread.php?t=2058351

so, check if you have the correct USB drivers installed for this card.

Even without a driver installed the device must appear using lspci.
I would assume a HW defect, or incorrect settings of the card (Jumpers if any) or the BIOS.
Does your BIOS show a list of attached PCI devices at boot (some BIOSses do for a short time before starting the OS)? If yes, do both parts of the card appear?
Does the card work in a different board or in a windows PC (if available)?

And what it does in different pc and different OS?
