Wikipedia / Lspci

lspci is a command on Unix-like operating systems that prints ("lists") detailed information about all PCI buses and devices in the system. It is based on a common portable library libpci which offers access to the PCI configuration space on a variety of operating systems.

Example usage

Example output on a Linux system:

Using lspci -v, lspci -vv, or lspci -vvv will display increasingly verbose details for all devices. -d [<vendor>]:[<device>] option specifies the vendor and device ID of the devices to display. Note that ":" can not be omitted, while the omitted <vendor> or <device> indicates "any value".

If many devices are shown as unknown (e.g. "Unknown device 2830 (rev 02)"), issuing the command update-pciids will usually correct this.

lsusb

lsusb is a similar command for USB buses and devices. To make use of all the features of this program, a system needs to use Linux kernel which supports the /proc/bus/usb interface (e.g., Linux kernel 2.3.15 or newer).

Example output on a Linux system:

hwinfo

hwinfo is for all the hardware. Hwinfo output reports for various computer models are collected in a public GitHub repository.

lshw

lshw is a subset of what hwinfo presents.

Other platforms

The equivalent command for FreeBSD is pciconf -l. pciconf can also perform other functions such as reading and writing PCI registers. For more information, see the man page.

The HWiNFO tool, which is not related to the hwinfo tool mentioned above, can be downloaded in binary form at no cost. It is claimed to be a "Comprehensive Hardware Analysis, Monitoring and Reporting for Windows and DOS".
