simple communication via USB
So anyway, I'm not entirely new to linux, but I'm far from an expert also.
I generally use debian or debian based distros.
What I am trying to do is figure out a simple way to tell a usb port to send a signal out one of its lines to trigger an action on a microcontroller.
Can anybody point me in the right direction or help me out? Is this too complicated a project for an amateur?
I've been searching the web to no avail but I may not be using the correct terminology as I am not that familiar with it.
Thanks in advance.
