# The basic pci.ids format is:
|
|
# - Vendor lines start with four (lower case) hex digits
|
|
# - Device lines start with one tab followed by four hex digits
|
|
# - Subsystem lines start with two tabs followed by two sets of four
|
|
# hex digits.
|
|
# - Class overrides for devices start with two tabs followed by a "C",
|
|
# followed by four hex digits with the class/subclass value.
|
|
# - Class lines start with a "C".
|
|
# - Comment lines start with a '#'.
|
|
# - Blank lines are ignored.
|
|
#
|
|
# We allow for extra lines to be appended to modify existing entries or
|
|
# add new ones. To add/modify Device entries without modifying the
|
|
# Vendor name, a special vendor name of '"' is used (mnemonic: "ditto").
|
|
# Similarly for adding subsystem names without modifying (or adding)
|
|
# a corresponding device entry. To rename an existing entry, simply
|
|
# provide the new name. To remove an existing entry, use the special
|
|
# name '-'.
