 //!                             LDD is loaded. OTGDI driver session is open

 //!                             OET inserted with SW9 set to B-Device

 //!                             No A device connected, A plug not connected

 //! @SYMTestActions 			1.	Call function on OTGDI to attempt role swap – BusRequest() 

 //!                             2.	Retrieve error event from error callback

 //! @SYMTestExpectedResults 	The call to BusRequest() will trigger the sending of an SRP.

 //!                             The SRP must be observed with a dual-trace oscilloscope measuring VBus and D+ and demonstrate the expected waveforms (Figure 5.5 in [R5])

 //!                             The A device, if present, should NOT raise VBus.

 //!                             The Error retrieved from the callback should be KErrUsbOtgSrpTimeout (-6691)

 //!                             Note this test case doesn’t, and isn’t intended to complete role swap.  That is tested in PBASE-USB_OTG-0681
