+record usb transfers
+^^^^^^^^^^^^^^^^^^^^
+
+All usb devices have support for recording the usb traffic. This can
+be enabled using the ``pcap=<file>`` property, for example:
+
+``-device usb-mouse,pcap=mouse.pcap``
+
+The pcap files are compatible with the linux kernels usbmon. Many
+tools, including ``wireshark``, can decode and inspect these trace
+files.
