+What: /sys/bus/usb/devices/INTERFACE/authorized
+Date: August 2015
+Description:
+ This allows to authorize (1) or deauthorize (0)
+ individual interfaces instead a whole device
+ in contrast to the device authorization.
+ If a deauthorized interface will be authorized
+ so the driver probing must be triggered manually
+ by writing INTERFACE to /sys/bus/usb/drivers_probe
+ This allows to avoid side-effects with drivers
+ that need multiple interfaces.
+ A deauthorized interface cannot be probed or claimed.

+Date: August 2015
+Description:

+ would be authorized by default.
