Try to omit the zener diodes. Most hosts accept 5 V levels. If that does not work, add two series diodes in the supply to drop the voltage to approx. 3.6 V. That's the cheapest solution.

Hi

I want to run atmega at 5V but I don't have Zener diodes and regulators on hand.

Is it OK if connect the USB power at pin 1 to atmega Vcc, and connect 2 diodes, 1 68 ohm resistor at D- pin, so that output of atmega pin is dropped to 3.x V ?

Thank you very much.
