Extending the USB dissector with subclass/protocol ID annotations?

Hi folks, Over the past few hours, I've been reading version 1.2 of the USB Forum's Communications Device Class and Ethernet Control Model Subclass specifications; and now I'm left wondering what the best/most lightweight way to annotate the *bInterfaceSubClass* and *bInterfaceProtocol* fields of "*Get Descriptor Response Configuration*" packets would be. That said, I'm not particularly interested in implementing every aspect of those specs, right now. Obviously, a set of new field pointers and value lookup tables would be necessary - although having looked at the source code for the HID and Hub dissectors, it seems that a lot of additional infrastructure is necessary*, just to connect those, in order to provide such annotations... Does anyone with greater familiarity of the USB dissector have any ideas? Thanks, Tyson. * (Much of what I consider to be extraneous for this case is naturally the "value added" bits that cover everything else in the appropriate specs) -- Fight Internet Censorship! http://www.eff.org http://vmlemon.wordpress.com | Twitter/FriendFeed/Skype: vmlemon | 00447934365844
