UGEEv2 tablets with battery can be connected using a USB cable or a USB Bluetooth dongle. When the Bluetooth dongle is used, the connection to that tablet can be lost because the tablet is out of the range of the receiver or because it was switched off using the switch placed in the back of the tablet's frame. After losing connection, the tablet is able to reconnect automatically and its firmware sends a special packet indicating that the device was reconnected. In response to this packet, the tablet needs to receive the same array of magic data it expects on probe to enable its interfaces. This patch implements a generic mechanism to hook raw events and schedule a work to perform any custom action.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
