Detailed Description

USB/HID keyboard device type.

Holds a reference to generic USB/HID device structure and keyboard-specific data, such as currently pressed keys, modifiers and lock keys.

Also holds a IPC phone to the console (since there is now no other way to communicate with it).

Note:
Storing active lock keys in this structure results in their setting being device-specific.
