Hello,

I analyze data that I sniff with a FPGA. To get the data from the FPGA to the 
computer I use USB transmission with the cypress fx2.

In the past I transferred the data via libusb to my computer and saved the raw 
data to disk and converted it with a tool to the pcap-file format.

Now I want to change this process. Is it possible to use the software, which is 
used to communicate with my cypress fx2, as a "costumized pcap-driver". Can I 
match the function calls of this software in the fassion of using this software 
to capture this data with wireshark?

In the chapter 8. "Packet capturing" of the wireshak developer guide the 
procedure is decribed how to add a new capture type to wireshark. There the 
communication with a serial device is realized with the device file if I'm not 
mistaken and this is not helping me.

Can you tell me where I can get further information about realizing how to 
capture packets with a proprietary driver or software without the use of the 
capture engines libpcap or winpcap?

Best regards
Jan
