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.

Using lspci -v, lspci -vv, or lspci -vvv will display increasingly verbose details for all devices. -d vendor> device>/code> option specifies the vendor and device ID of the devices to display. Note that ":" can not be omitted, while the omitted or 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 th
/proc/bus/usb
interface (e.g., Linux kernel 2.3.15 or newer).

Example output on a Linux system:
# lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 004: ID 06cb:0081 Synaptics, Inc.
Bus 003 Device 003: ID 5986:2115 Acer, Inc Integrated Camera
Bus 003 Device 002: ID 05e3:0608 Genesys Logic, Inc. Hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 0bda:b023 Realtek Semiconductor Corp. RTL8822BE Bluetooth 4.2 Adapter

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.How to interpret lshw output

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 th
man page

Th
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 "system information and diagnostics comprehensive hardware analysis, monitoring and reporting for Windows and DOS".
