 	@SYMTestActions 			1.  Enumerate A

                                 2.  Get token for interface 0 (token 0) – save token 0

                                 3.  Open interface 0 with token 0

                                 4.  Get token for interface 1 (token 1)

                                 5.  Open interface 1 (token 1)

                                 6.  Open pipe on interface 1, endpoint 2

                                 7.  Queue bulk in transfer on pipe

                                 8.  Vendor dependant request : Disconnect A- Connect C sent to device A

                                 9.  Transfer completes with cancelled error code

                                 10. Close interface 0

                                 11. Enumerate C

                                 12. Try to open interface 0 with previous token 0, fails since token is invalid

                                 13. Get token for interface 0 (token 2) 

                                 14. Open interface 0 (token 2)

                                 15. Vendor dependant request : Disconnect C- Connect A sent to device C

                                 16. Close interface 0

                                 17. Enumerate A

                                 18. Get token for interface 0 (token 3)

                                 19. Open interface 0 with token 3

 	@SYMTestExpectedResults 	Unable to open any interface using expired token, Transfer cancelled on disconnection

 	@SYMTestStatus				Implemented
