+Description:
+ This is visible only for bridge devices. If you want to reset
+ all devices attached through the subordinate bus of a specific
+ bridge device, writing 1 to this will try to do it. This will
+ affect all devices attached to the system through this bridge
+ similiar to writing 1 to their individual "reset" file, so use
+ with caution.
