From 969678c09877fd1116be6ae304e59a27658226c2 Mon Sep 17 00:00:00 2001 From: Robert Baldyga Date: Tue, 13 Jan 2015 14:56:28 +0100 Subject: tools: ffs-aio-example: use endpoint addresses from descriptors This makes examples more platform independent and more compatible with USB standard, as endpoint addresses in given interface may differ between hardware platforms or even between configurations in single USB device.
