How to identify a device > PCI
How to "identify" the PCI-like devices (AGP, PCI-Express, CardBus, Express Card, etc) that are connected to you computer.
Many people simply use lspci, which is available on every Debian system, to list the device on their computer. hardinfo is available to install and use with GTK based desktops such as GNOME, MATE or Xfce. users can install and use the method. kinfocenter is available in KDE Plasma Desktop.
PCI-id
PCI devices are identified by a pair of hexadecimal numbers. 1014:003E for example.
- The 4 first hexadecimal digits are the Vendor ID (1014 = IBM)
- The 4 last hexadecimal digits are the Device ID (003e = 16/4 Token ring)
There is also some sub-vendor-id, sub-vendor-id (to identify the computer/vendor implementation), PCI function and class, see the references section for more information.
Some of the devices (device-ids) handled by Debian are listed in the DeviceDatabase/PCI page.
lspci
lspci (from the pciutils package) is the standard tool to query the devices connected to any PCI compatible bus.

Notes regarding the example above:
- 104c:ac56 is the cardbus bridge ("controller")
- 1317:1985 is a PCCard (32-bit Cardbus) Ethernet Adapter.
if your device description says "Unknown device", you can update your local pci-id definitions by running the update-pciids command as root.
/usr/share/misc/pci.ids - A text file mapping vendor IDs and device IDs to a text description.
You can shorten the above list with grep:
$ lspci -nn | grep Network 03:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG Network Connection [8086:4227] (rev 02)
HardInfo
hardinfo (screenshots) (from the hardinfo package) has a "PCI Devices" section about the PCI cards installed on the system.
KInfocenter
KDE's KInfoCenter (in K Menu / System / Info Center) (screenshots) (from the kinfocenter package) has an information page on the PCI cards.
Note: KInfoCenter provides the PCI device names, not PCI IDs.
discover
discover (from the discover package) can list PCI devices:

discover uses its own files: /lib/discover/pci-busclass.xml, /lib/discover/pci-device.xml, /lib/discover/pci-vendor.xml
Manual
/proc/bus/pci/devices
If lspci isn't available (!), you can display the content of /proc/bus/pci/devices to list vendor and device IDs.
$ cat /proc/bus/pci/devices
/sys/bus/pci
If lspci isn't available (!), you can browse /sys/bus/pci (assuming sysfs is mounted on /sys). The Linux kernel sysfs PCI documentation (also available in the linux-doc packages) gives details about the files in /sys/bus/pci.
