//! @SYMTestCaseID				PBASE-T_OTGDI-0678

//! @SYMTestCaseDesc			B-Device Role-swap attempt. VBUS up, b_hnp_enable, bus suspended

//! @SYMFssID 

//! @SYMPREQ					1305

//! @SYMREQ						8929

//! @SYMTestType				UT

//! @SYMTestPriority			1 

//! @SYMTestActions 			1.	A-Device raises VBus

//!                             2.	A-Device and B-Device wait to arrive in default roles (A-Host, B-Peripheral)

//!								3.	B-Peripheral waits to arrive in configured state, A-Device waits to become A-Peripheral

//!								4.	A-Host enumerates newly attached peripheral, and suspends it

//!								5.	B-Peripheral waits to arrive in suspended state

//!								6.	B-Device makes a bus request, HNP occurs

//!								7.	A-Device and B-Device arrive in swapped roles (B-Host, A-Peripheral)

//!								8.	A-Peripheral waits to arrive in configured state, B-Device waits to become B-Peripheral

//!								9.	B-Host enumerates newly attached peripheral, and suspends it

//!								11.	A-Peripheral waits to arrive in suspended state

//!								12.	Role swap occurs automatically. Test repeats from step 2, 3 times.

//!								13.	A-Device drops VBus

//!								14.	A-Device and B-Device both observe VBus dropping.

//!								

//! @SYMTestExpectedResults 	VBus rises, followed by multiple role swaps, followed by VBus dropping (within 30 seconds)

//! @SYMTestStatus              Defined
