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 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 .

The 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".
