must execute mode setting for each endpoint by using the value that is appointed by
endpoint-descriptor in the config-descriptor. After finish mode setting, set Configured
bit (Bit2) to “1” before accessing EOP register. When this bit is set to “1”, Addressed bit
(Bit1) is set to “0” automatically.
