From 2922440e42230d3d1b63397e99efa331f499c755 Mon Sep 17 00:00:00 2001 From: John Keeping Date: Tue, 12 Nov 2019 14:01:40 +0000 Subject: [PATCH 05/10] linux_udev: silently ignore "bind" action When a driver is bound to a device, udev emits a "bind" action that causes libusb to log an error message: libusb: error [udev_hotplug_event] ignoring udev action bind Since we know this action is not relevant for libusb, silently ignore it to avoid people thinking there is something wrong. There is already a debug log entry for the action, so there is no need to add a duplicate here.
