Information about usb devices and peripherals

prakashpms · 08-19-2009, 01:25 PM

How can we find out the hardware information about the usb devices or other peripherals like PS2 keyboard, mouse, webcam etc? Is there a command to find out the exact hardware inventory information? lsusb or lshw doesn't give descriptive hardware information like manufacturer etc.

when using lshw.. it shows vendor for me.

lsusb -v is pretty descriptive.

also try looking in dmesg or sudo tail -f /var/log/messages while plugging in a usb device.

I don't see any class for keyboard/mouse etc in lshw output. It shows only the keyboard controller as below.

<capability id="int9keyboard" >i8042 keyboard controller</capability>

How you are getting it? what is the class?

Hi schneidz,

lsusb -v is descriptive. Are there similar stuff to find out other peripherals like serial, ps2 etc. udev provides alerts but finding it difficult to match the pattern. Is there anything under /sys, /proc filesystme through which i can get. I see keyboard, mouse under input devices but vendor information is missing.

i think you were lucky enough to get that much info about your keyboard in lshw(i dont even get that

).. actually i meant that in general it shows the vendor name for peripheral devices like ethernet, sound, graphics etc etc.

i dont know if ps/2 devices identify themselves... you can try lspci maybe ?
