Bus Pirate v4 is alive!
Bus Pirate Community Firmware v7.0 is running on the new Bus Pirate v4 hardware with direct PIC-based USB connection. Back in time, it started out slow at v5.9 because USB support is hacked into replacements for the existing serial port functions, but the latest v7.0 firmware is working great

Manufacturing test plan
The manufacturing test plan will use the Bus Pirate internal hardware self-test.
- Place a jumper between the +3.3V pin and the ADC pin
- Plug the Bus Pirate into USB
- Open a terminal to the Bus Pirate COM port. Type '~' to start the self test
- Follow the instructions and verify the LEDs
The manual procedure will be replaced with a self-test application.
