------- Comment #2 from florent.drouin@xxxxxxxxxx  2007-11-26 09:50 GMT -------
in dissect_usb_endpoint_descriptor, a new conversation is added with
conversation_add_proto_data(conversation, proto_usb,
usb_trans_info->interface_info);
and the pointer class_data is not initialized (because we have not a structure
usb_conv_info_t)

It seems, there is a conflict, with a previous conversation added with
get_usb_conv_info(conversation);

The new conversation (from usb_endpoint) is taken, with the wrong info, whereas
the first conversation with usb_conv_info should be used.
