Hello list,
I'm currently trying to write a wireshark disector that slices up a
specific custom USB device. Now I've read the (BTW absolutely
marvellous!) documentation about how writing plugins and I can get
disectors to work which do basic stuff (like recognize IP packets or
such). But since I want to disect USB (which appearently is also coded
in a module), when I call:
dissector_add("usb.data_flag", 0x1, sbig_handle);
Wireshark cries out in pain:
ERROR:packet.c:697:dissector_add: assertion failed: (sub_dissectors)
The problem, I think, is that "usb.data_flag" is not a registered
subdissector table. packet-usb.c only registers 2 dissector tables:
usb_bulk_dissector_table = register_dissector_table("usb.bulk",
"USB bulk endpoint", FT_UINT8, BASE_DEC);
usb_control_dissector_table = register_dissector_table("usb.control",
"USB control endpoint", FT_UINT8, BASE_DEC);
