I build the circuit over-and-over, but Zener U$S2 (connected with r2/3) becomes very hot and windows still said that he couldn't find the right drivers for this device.

I bought the 1N5227B. In your article you speak about the 1N5227B-TAP. See comparision:

Whats the difference between them?

suffixes on small parts refer to some specification in the data sheet... Temperature, case type, lead materials, etc.   Either should work.

If the zeners are hot, you have miswired something! Disconnect, and recheck.  Go back to rancidbacon's article and double-check.

Please, if you are not an advanced experimenter that understands electronics, you should not attempt mucking around with your PC USB... YOU CAN DAMAGE THE PORT.

PS: drivers are HID and are part of every Windows base package.

Works!
The circuit was wrong.
In the usb-connector I used, the sequence of D+, D- etc. was different of the circuit at hackster.io.
I expected that the sequence at the picture was the same of at a real usb-connector. But it was not... :-(

I'm happy to play with it.
Thanks for supporting me.

@jmnijsse:
GREAT, glad it all works.

Another question:

How is it possible to use the millis() function, because of timer0 is disabled?
Is millis() switchable at different timers?
