Uumas I believe you are right. I just found a Usb A Male to Usb A Male cable and I plugged my computer in to the dock and it didn't send the payload or even recognize the switch at all. So case closed I guess. Thanks for the input!
ahh right I was thinking of the full size usb but now you reminded me that all of the dongles use usb c. still curious if a payload can be pushed through the dock though.
