In the interest of making long-term branch maintenance incur as little technical debt on us as possible, we should not maintain any files on the branch we are not actually using. This has the added effect of making it extremely clear when merging CLs from the main branch when changes have the possibility to affect us. The follow-on CL adds a convenience script to actually pull updates from the main branch and generate a CL for the update.

-# Rules for Google Case Closed Debugging devices.
-#
-# The first rule matches the google VID and records the product name, USB bus
-# number and USB device path (the device path is the list of hub ports between
-# the root and the device). This becomes a unique directory name under which
-# later rules can create symlinks. If this rule doesn't match udev will skip
-# the rest of this files rules.
-#
-# This rule intentionally matches using SUBSYSTEMS and ATTRS instead of
-# SUBSYSTEM and ATTR so that the GOOGLE_CCD_NAME is available to all nodes
-# that descend from a Google USB device (this includes all USB interface nodes
-# as well as all of the TTY nodes derived from CCD USB interfaces).
-#
-SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ENV{GOOGLE_CCD_NAME}="$attr{product}-$attr{busnum}-$attr{devpath}"
-
-#
-# Force ModemManager to ignore all Google case closed debug devices. It would
-# be better to just ignore the case closed debug serial console interfaces, but
-# ModemManager doesn't look at the usb_interface udev node, it looks at the
-# usb_device node, so you have to mark the entire device as incompatible with
-# ModemManager.
-#
-# This node could lose the match against the usb_device DEVTYPE and still work,
-# it would just add extraneous ID_MM_DEVICE_IGNORE tags to the TTY and USB
-# interface nodes.
-#
-SUBSYSTEM=="usb", ENV{GOOGLE_CCD_NAME}!="", ENV{DEVTYPE}=="usb_device", ENV{ID_USB_INTERFACES}=="*:ff5001:*", ENV{ID_MM_DEVICE_IGNORE}="1"
