Version: 1.0, 1.1, 1.2, 1.3 Title: permission denied error during installation or upgrade on new_id. Symptom: during installation or start, a "Permission denied" error writing to /sys/bus/usb-serial/drivers/option1/new_id Analysis: /sys/bus/usb-serial/drivers/option1/new_id may not exist, especially on Debian Etch kernels which predate the new_id mechanism. Workaround: ignore, harmless. Action Plan: change /etc/init.d/bp3 to gracefully report issue. From: Andreas Baitis
