I have a couple of numeric USB keyboard (just 0..9 and "OK" and "Esc")
I need to read what is pressed to Arduino.
How should I connect the for wires (presumable gnf, vcc and d0 and d1) to read some data from d0 1nd d1?
Keyboard data comes in packets imho in usb but I reckon I can figure which is "4" an which is, say "1" by just looking how the packets differ. Would this work?
