Please specify Cr-* of the system to which this bug/feature applies (add

Steps To Reproduce:
(1)First of all, our company's infrared touch screen is transmitted through the USB data, and the device is free drive, just like the mouse, keyboard.At the same time, our devices support multi-touch.Connected to the Windows system, the same as the operation of mobile phone screen.
(2)Our touch-screen devices are not supported on all Chromebooks, and there is no corresponding event response to the touch-sensitive box. For example, on Windows, I click the touch box and the cursor changes to a small dot.
(3)Because Chrome OS kernel is Linux 3.14, based on the function of linux input subsystem, I use the command: cat dev / input / event5 | hexdump, crawl asus C100PA-DB02 chromebook capacitive screen click event data, the data is Input subsystem under the event data, and then I will be our company's devices connected to the Chromebook via USB to the same method and operation to capture the same event data, comparing the two data did not find any similarities and differences.But the Chromebook can perfectly support the operation of the capacitive screen, for example, through the capacitive screen can be drawn in the chrome browser drawing plug-in, you can capacitive screen to open the application and other related operations. However, these things our device does not work on the chromebook at all.What's wrong?
(4)The same data, why the capacitive screen will respond and our products do not respond?
Expected Result:So that our device can be as capacitive screen that can operate on the chromebook.

(5)Thank you for your answer!

Actual Result:The underlying data has, but the upper application does not seem to support
