Very, very good point, I'd completely forgotten about that, libpcap is just the sniffer half. Its complement is libnet, and it seems to have Windows support as well. Somehow I forget that this sort of stuff requires two separate packages. In the general case, I don't think a great case could be made for using libpcap+libnet to implement networking tools for normal production use, rather than using the OS stack. But your case isn't the general one; you've got this simple cable with two endpoints and you want a single application to talk over it. In some abstract sense, using the OS's whole networking stack is arguably "cleaner", but it's understandable that you don't want to force your users to have to configure networking. I think that using libpcap+libnet together with the standard network-interface low-level drivers is a cleaner solution than attempting to write and maintain a new custom USB protocol implementation. -Bennett
