Subject: [PATCH 05/10] linux_udev: silently ignore "bind" action
|
|
|
311d97 |
|
|
|
311d97 |
When a driver is bound to a device, udev emits a "bind" action that
|
|
|
311d97 |
causes libusb to log an error message:
|
|
|
311d97 |
|
|
|
311d97 |
libusb: error [udev_hotplug_event] ignoring udev action bind
|
|
|
311d97 |
|
|
|
311d97 |
Since we know this action is not relevant for libusb, silently ignore it
|
|
|
311d97 |
to avoid people thinking there is something wrong.
|
|
|
311d97 |
|
|
|
311d97 |
There is already a debug log entry for the action, so there is no need
|
|
|
311d97 |
to add a duplicate here.
