Live Capture

USB live capture is now possible, currently the following Audit Records exist: USB and USBRequestBlockSetup.

To capture USB traffic live on macOS, install wireshark and bring up the USB interface:

$ sudo ifconfig XHC20 up

Now attach netcap and set baselayer to USB:

$ net.capture -iface XHC20 -base usb

Offline from dumpfile

To read offline USB traffic from a PCAP file use:

$ net.capture -r usb.pcap -base usb

Don't forget to set the -payload flag if you want to preserve the data being transmitted!
