sk1mo and primo1337 over at xboxhacker.org have released an update to their ATtiny2313 based DIY hardware design which restarts and logs boot times automatically on RGH modded Xbox 360 consoles. The RGH Butler design now features USB support (FT232R), auto flash CPLD via NandPro, and the boot process is checked via postbit 0 instead of the Xbox 360 serial UART."
