3.17 PS2 Devices PnP configuration
3.17.1 Hot Plug-and-Play support
The KBC watches both external devices, checking if the devices have recently been
plugged in or unplugged. The Hot plug ability of external PS2 devices feature detects
the attachment or removal of these devices.
3.17.2 Hot swapping control
When the device is plugged in, the software automatically initializes the state of that
device, checks port swapping, and sets up the KBC to handle dual-device operation.
In dual-device operation, the internal device is set in the same state as the external
device. When the external device is unplugged, the internal device becomes the
primary device.
