Plugins rate themselves on their ability to obtain information from various device types and report their ratings to the plugin manager so that it can choose the best plugin for filling in data fields.
Device publisher | Supporting plugins |
---|---|
usblauncher_otg | ipod, dvd, mediafs, audiocd, generic |
mmcsdpub | generic |
cdpub | dvd, audiocd, generic |
Although the plugin manager ranks the plugins based on their ability to extract information, the particular plugin used for filling in data fields also depends on the device type.
Suppose you connect a Media FS device through a USB port. If the USB launcher service requested the device name and ID, the plugin manager would first invoke the ipod plugin but this plugin would fail to fill in the fields because the device isn't an iPod. Next, the plugin manager would invoke mediafs, which would try to obtain the requested information. If that second plugin failed for whatever reason, the plugin manager would invoke generic. So, the extra device information can come from any plugin that supports the publisher.
