Hi, I want to capture the USB traffic for my app running on High Sierra. I brought the if XHC20 up and can capture the traffic using Wireshark nightly builds. But I only see incoming traffic (from device to host) but not the other direction. Any ideas what is going wrong here?Starting the IF:> sudo ifconfig XHC20 upAfter that I can select the IF in Wireshark and start capturing packets. I can see incoming traffic from attached devices but not the outbound messages.
