使用 -v 可產生更詳細的清單：

linux:~ # lspci
[...]
02:08.0 Ethernet controller: Intel Corporation 82801DB PRO/100 VE (LOM)\
 Ethernet Controller (rev 81)
        Subsystem: Fujitsu Siemens Computer GmbH: Unknown device 1001
        Flags: bus master, medium devsel, latency 66, IRQ 11
        Memory at d1000000 (32-bit, non-prefetchable) [size=4K]
        I/O ports at 3000 [size=64]

關於設備名稱解析的資訊是從檔案 /usr/share/pci.ids 取得。本檔中未列出的 PCI ID 標記為「不明設備」。

參數 -vv 可產生所有可供程式查詢的資訊。如果要檢視純數值，應使用參數 -n。
