 //! @SYMTestCaseID				PBASE-T_OTGDI-0681

 //! @SYMTestCaseDesc			B-Device SRP/HNP attempt, A-Device detects SRP, responds with BusRespondSrp

 //! @SYMFssID 

 //! @SYMPREQ					1305

 //! @SYMREQ						8929

 //! @SYMTestType				UT

 //! @SYMTestPriority			1 

 //! @SYMTestActions 			1.	B-Device triggers SRP, A-Device waits to detect SRP

 //!								2.	A-Device calls BusRespondSrp

 //!								3.	A-Device and B-Device arrive in swapped roles (B-Host, A-Peripheral)

 //!								4.	A-Peripheral waits to arrive in configured state, B-Device waits to become B-Peripheral

 //!								5.	B-Host enumerates newly attached peripheral, and suspends it

 //!								6.	A-Peripheral waits to arrive in suspended state

 //!								7.	Role swap occurs automatically

 //!                             8.	A-Device and B-Device wait to arrive in default roles (A-Host, B-Peripheral)

 //!								9.	B-Peripheral waits to arrive in configured state, A-Device waits to become A-Peripheral

 //!								10.	A-Host enumerates newly attached peripheral, and suspends it

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

 //!								12.	B-Device makes a bus request, HNP occurs. Test repeats from step 3, 3 times.

 //!								13.	A-Device drops VBus

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

 //!								

 //! @SYMTestExpectedResults 	SRP is detected and responded to. VBus rises, followed by multiple role swaps,

 //!								followed by VBus dropping (all within 30 seconds)

 //! @SYMTestStatus              Defined
