02:08.0 Ethernet controller: Intel Corporation 82801DB PRO/100 VE (LOM) \
    Ethernet Controller (rev 81)

Using -v results in a more detailed listing:

mercury:~ # lspci -v
[...]
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]
        Capabilities: [dc] Power Management version 2

Information about device name resolution is obtained from the file /usr/share/pci.ids. PCI IDs not listed in this file are marked Unknown device.

The parameter -vv produces all the information that could be queried by the program. To view the pure numeric values, use the parameter -n.

11.3.2 USB Devices: lsusb

The command lsusb lists all USB devices. With the option -v, print a more detailed list. The detailed information is read from the directory /proc/bus/usb/. The following is the output of lsusb with these USB devices attached: hub, memory stick, hard disk, and mouse.
