    Thread Summary
    
                The user encountered issues with test patterns from a HSETT device not passing through the ADuM4165 USB 2.0 isolator during TekExpress USB2 compliance tests. The support engineer confirmed that certain transmitted tests (EL_2, EL_3, EL_6, EL_7) can be measured with modifications, such as connecting a peripheral to the ADuM4165 at the start of the test procedure. The user was also directed to contact the support engineer for further information on the test function failure.

    Product Number:  ADUM4165  
    
    		        		    		    
    
		    		    
		    			
    
			    
    When running the TekExpress USB2 test software through an ADuM4165 USB 2.0 isolator, the test pattern from the HSETT device are not passing through the ADuM165. Is this a known issue with this isolator and other USB isolators?
    

    How can I perform standard USB2.0 high-speed compliance tests when an ADuM4165 is in the USB path?

        Answer from Prasanthi Yerra:
        

        Thank you for specifying details on the setup .
        

        It is possible to measure the transmitted tests : EL_2,EL_3,EL_6,EL_7 ,with a few modifications such as connecting a peripheral to ADUM4165 at the beginning of test the procedure.
        

        Please go through the attached ppt and follow the steps for executing the tests (See attachment to follow).
