From 5e9eb156c003dc7f8f92287bfad0251d6c5d0ef9 Mon Sep 17 00:00:00 2001 From: Martin Pitt Date: Tue, 15 Feb 2011 13:06:18 +0100 Subject: [PATCH] 60-persistent-input.rules: Support multiple interfaces Create /dev/input/by-id symlinks containing the USB interface number so that each interface in a multi-interface USB input device gets its own symlink.
