The libpcap code could just ignore what the usbmon module specifies and just explicitely call gettimeofday() instead. USB packets probably arrive at such very slow rate anyway that a few gettimeofday() calls are unlikely to cause any performance issues. However, much more important is the apparent offset by one for the captured data which renders all data (excluding usb header and setup) semi-useless. _______________________________________________ Wireshark-dev mailing list Wireshark-dev@wireshark.org http://www.wireshark.org/mailman/listinfo/wireshark-dev
