To see PCI connected devices, from the command line do:

lspci

For USB connected devices...

lsusb

For a list of options for each, add "--help" after the respective commands... without the quotes of course....

[daark.child]

Other commands to look at are hwinfo and lshw. These may not be installed by default, but you can use your distributions package manager to install them.

lspci & lsusb wil display the list of devices connectd to usb r pci,
to get information about serial port devices like mouse, keyboard & parallel port devices lik printer, how can i get these information,


Thanks

As daark.child said -- hwinfo. Install and run:

hwinfo --short

See here for a lot of info on this subject.

Alternatively, you can try udevinfo.

Especially if you want to extract the ouput and use it for another program. Because udevinfo outputs are all in name and value pairs, so it is easier to parse.

Both udevinfo and lshw are pretty good
