-Subject: [PATCH] udev: implement hwdb USB ID lookup from usb.ids (#80)
-
-Replace the four stub udev_hwdb_*() functions with a working
-implementation that looks up vendor and product names from a
-usb.ids database file (e.g. provided by the hwdata package).
-
-udev_hwdb_get_properties_list_entry() parses the file for USB
-modalias strings of the form "usb:vVVVVpPPPP" (product lookup)
-or "usb:vVVVV" (vendor lookup), and populates the entry list with
-ID_MODEL_FROM_DATABASE or ID_VENDOR_FROM_DATABASE properties.
-
-Lines are read via POSIX getline() so the buffer grows as needed
-on long usb.ids entries.
-
-The path to the usb.ids file is set at build time via the
-USB_IDS_PATH Makefile variable, which defaults to
-${SHAREDIR}/hwdata/usb.ids.
