micronucleus is a 2Kb boot loader that provides a bit banged USB interface for directly updating user code without teh need for a programming device or dedicated USB to UART/Serial hardware.

A new ATtiny85 chip will need a time operation, i.e., be flashed with this bootloader. avrdude is a useful solution for this, and the following demonstrates such process with a Bus Pirate.
Check proper connectivity with chip via Bus Pirate connected at ttyUSB0
