In the Linux 2.6 kernel, hotplugging has been integrated with the driver model core so that any bus or class can report hotplug events when devices are added or removed. Quite a few subsystems now support hotplugging; the list at this site is not currently exhaustive.

hotplug is a program which is used by the kernel to notify user mode software when some significant (usually hardware-related) events take place. An example is when a USB or Cardbus device has just been plugged in. This is useful for automatically loading and setting up drivers, packaged either as kernel modules or as user mode programs.

No. 1 is unlikely to be supported. No. 2 may supported by libata, on a per-driver basis, for all hardware that supports it. No. 3 is supported by libata, for most hardware and devices that support NCQ. Hotplug support. libata supports both controller hotplug ("yank the card") and device hotplug ("yank the drive").

USB Modutils Support¶. Current versions of module-init-tools will create a modules.usbmap file which contains the entries from each driver’s MODULE_DEVICE_TABLE.Such files can be used by various user mode policy agents to make sure all the right driver modules get loaded, either at boot time or later.
https://en.wikipedia.org/wiki/Hot_swapping
Machines that support hot swapping need to be able to modify their operation for the changed configuration, either automatically on detecting the change, or by user intervention. All electrical and mechanical connections associated with hot-swapping must be designed so that neither the equipment nor the user can be harmed while hot-swapping.
