Universal Serial Bus Interfaces
States powered, attach, defaultFS/HS, suspendFS/HS are implemented in the USB controller and are
communicated to the DCD using the following status bits:
It is the responsibility of the DCD to maintain a state variable to differentiate between the DefaultFS/HS
state and the Address/Configured states. Change of state from Default to Address and the Configured
states is part of the enumeration process described in the device framework section of the USB 2.0
Specification.
