How to interface multiple USB UIRT devices from one machine using C++. In the API list I do not see any API to distinguish between different USB hardware, though I came across an API in this post http://www.usbuirt.com/phpBB2/viewtopic.php?t=895. The API is UUIRTOpenEx("USB-UIRT", 0, NULL, NULL).
My requirement is to simultaneously drive multiple USB UIRT hardware each on its own thread if possible, to control multiple STBs.
