lspci is a command on Unix-like operating systems that prints 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[edit]

Example output on a Linux system:

# lspci
00:00.0 Host bridge: Intel Corporation 82815 815 Chipset Host Bridge and Memory Controller Hub (rev 11)
00:02.0 VGA compatible controller: Intel Corporation 82815 Chipset Graphics Controller (CGC) (rev 11)
00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev 03)
00:1f.0 ISA bridge: Intel Corporation 82801BAM ISA Bridge (LPC) (rev 03)
00:1f.1 IDE interface: Intel Corporation 82801BAM IDE U100 Controller (rev 03)
00:1f.2 USB Controller: Intel Corporation 82801BA/BAM USB Controller #1 (rev 03)
00:1f.3 SMBus: Intel Corporation 82801BA/BAM SMBus Controller (rev 03)
00:1f.4 USB Controller: Intel Corporation 82801BA/BAM USB Controller #2 (rev 03)
00:1f.5 Multimedia audio controller: Intel Corporation 82801BA/BAM AC'97 Audio Controller (rev 03)
01:03.0 CardBus bridge: O2 Micro, Inc. OZ6933/711E1 CardBus/SmartCardBus Controller (rev 01)
01:03.1 CardBus bridge: O2 Micro, Inc. OZ6933/711E1 CardBus/SmartCardBus Controller (rev 01)
01:0b.0 PCI bridge: Actiontec Electronics Inc Mini-PCI bridge (rev 11)
02:04.0 Ethernet controller: Intel Corporation 82557/8/9/0/1 Ethernet Pro 100 (rev 08)
02:08.0 Communication controller: Agere Systems WinModem 56k (rev 01)

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

lsusb[edit]

lsusb,[1] is a similar command for USB buses and devices. To make use of all the features of this program, you need to have a Linux kernel which supports the /proc/bus/usb interface (e.g., Linux kernel 2.3.15 or newer)

hwinfo[edit]

hwinfo is for all the hardware. lshw is a subset of what hwinfo presents.

Other platforms[edit]

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.

See also[edit]

  • dmesg — prints the message buffer of the kernel
  • uname — prints the name, version and other details about the current machine and the operating system
  • dmidecode — prints information from DMI interface from BIOS.
