Dear Sirs
I would like to know what about HID(HUMAN INTERFACE DEVICES).

The net definition says:

"A human interface device or HID is a type of computer device that interacts directly with and takes input from humans, such as the computer keyboard, computer mouse, joystick, graphics tablet, and the like. The term was coined by Microsoft. "

My question is are these HIDs only for USB type devices or for all types.
For example
They say example of HID is keyboard. wat type of Keyboard
--USB Keyboard
--or the traditional ones
--or both

Please let me know!!!
A much more precise definition would be appreciated
Thank you
