Hello PanamaTom,


Welcome to Community@Insignia!


As the NS-PU99501 product you've mentioned is a cable, I recommend consulting the support materials for the device(s) to which it is connected for further assistance.


Thank you for writing to us.

John, Thanks for the info. I found how to change the port in device manager under the device / properties / advanced settings. you can change it to any port that there are no conflicts.
