This article describes an implementation of the DIY USB password generator. It is a small USB HID keyboard device that types a password stored in EEPROM every time it’s attached.
The board uses different pin connections to USB to the original, and requires a hardware jumper from D+ (PB4) to INT0 (PB2).
In the process of changing the code, I updated the V-USB driver. That necessitated quite a few changes to source code.
The updated code was compiled, and tested just fine.
