 * '''Launchpad Entry''': UbuntuSpec:desktop-lucid-jockey-hotplug-support

== Summary ==

Jockey supports printers, Wifi cards, and DVB-T cards, which often come with USB and are hotplugged. Instead of just triggering Jockey to check for drivers once after installation, we bring up Jockey when such a device is plugged in and needs firmware.

== Release Note ==

The check for required hardware drivers ("Jockey") is now run when hotplugging hardware which needs firmware, such as DVB-T or Broadcom WLAN USB sticks.

== Design ==

 * When a device is plugged in which needs firmware, the kernel triggers a "firmware" subsystem uevent.
 * Add code to `update-notifier` to watch for those uevents, check if the requested firmware file is missing, and if so, launch `jockey-gtk` (or `jockey-kde` in update-notifier-kde).
 * Check modules which have jockey handlers (b43, wl, dvb-*) for having correct firmware file links in modinfo. E. g. `b43` has a wrong one, which needs to be fixed in the kernel.

== Implementation ==

See blueprint work items.

== Test/Demo Plan ==

 1. Ensure that you do not have firmware installed yet: no `/lib/firmware/b43/`, and the `linux-firmware-nonfree` package is not installed.
 1. Log into a GNOME or netbook session.
 1. Plug in an USB device which needs firmware, such as a DVB-T stick or a hotpluggable Broadcom Wifi device.
 1. After some seconds, Jockey should pop up, offering the firmware package/download.
 1. Regardless of whether you installed it or not, if you remove the device and plug it back in, Jockey should not pop up again.
