You are exactly right - I thought I could use any expression which I
could also use within wireshark (e.g. usb.data_flag == 1). However, it
seems I cannot.
Using usb.bulk does not do the trick, however - it does not seem to
register correctly (although it does not give the above exception). When
I change the line to
dissector_add("usb.bulk", 0x1, sbig_handle);
it just does not recognize bulk trasnfers as the SBIG protocol. How do I
then use the dissector_add command to achieve what I want?
Kind regards,
Johannes
