webOS - Nexmosphere

Hello Community,

I have a question about a possible integration between an LG webOS Signage screen and a Nexmosphere controller.
I have an XN-135-M8L controller connected by USB to an LG webOS Signage screen running webOS 4.1.0.
I would like to know if it is possible for webOS to detect this USB connection and if it is possible to read and write data on this controller from my Javascript/HTML software installed on the screen.

Thanks in advance.
