List of PCI and USB Devices - Linux and Windows

Sometimes it's necessary to check devices installed on a PC. In Linux it is quite simple - command

$ lspci -h

gives out available options for listing PCI devices.
For example,

$ lspci -nn

shows up both textual and numeric ID's.

There is a similar command for USB devices:

$ lsusb -h

For the same purposes in Windows there is a nice program devcon.exe - it can be downloaded from http://support.microsoft.com/kb/311272.
For instance, command

> devcon findall PCI*

lists all PCI devices. The following command shows up all PCI devices with assigned system resources:

> devcon resources PCI*
