A Hard Reset will cause the controller to re-enumerate.
In the case of a Soft Reset, after sending the command, the controller will acknowledge
(ACK) the transfer, but the command will not yet be completed. Before sending any other
commands, the host should poll with GetStatus until the command status field returns
"Soft Reset Occurred," "Command Complete," or "Fail". Any timeout for this status
polling should be 2 seconds minimum.
Set Feature –Restore Defaults
