In this post I’ve documented reverse engineering efforts by myself and others and present a small C utility for pcap packet capture on the Linux platform. Two output formats are supported:

Posted by Joe Desbonnet at It is possible to check if a device is bound to a kernel driver and unbind it in libusb 1.

I have updated this tool to us the new hardware version based on the MRF24J40 chip.

I would love to be able to check for this and unbind programatically, but I don’t know how to go about it. Main menu Skip to primary content. I guess we are all spoiled by Wireshark, but I was hoping for more detail and a better UI.

The Python script is available here. In this post I’ve documented reverse engineering efforts by myself and others and present a small C utility for pcap packet capture on the Linux platform.

This will be incorporated in the next release — version 0. A level of 0 implies no debugging default9 maximum verbosity. It comes with free Windows-only software.

You’ll probably need to be logged in as root to do all of these things. Zena Packet Capture Tool. Make note of it. Linux Microchip Zena data, isn’t it beautiful?

Awesome work and thanks for making zea tool available as open-source. Using the SnoopyPro USB snifferI was able to look at the USB packets, observing data from frames shown by the sniffer, as well as recording the configuration activity based on the channel I specified to capture on.

The Zena sniffer can save a capture in a proprietary file format microochip, and can export selected frames to the clipboard in space-delimited hex bytes. With no Linux support, I decided to write my own user space Linux driver to capture packets with the goal microchi; integrating it into libpcap captures and other tools including Kismet Newcore.

This is how to “unbind” it: Each chunk is prefixed with a timestamp obtained from the host computer -v will display version information and quit. Two output formats are supported: Using PyUSB with the excellent Pymissle project by Scott Weston as an example, I quickly put together a tool that can set the channel number and capture frames from the Zena device, dumping the hex bytes to stdout. On Ubuntu you can do sudo bash to avoid prefixing everything with “sudo”.

A number between 11 and 26 is expected. The packet capture output is sent to standard output.

With this information, it was straightforward to identify the USB endpoint 0x01 as the control channel for setting the channel and USB endpoint 0x81 as the data endpoint for delivering frames.

Prior to running you need to make sure the ZENA device is “unbound” from any kernel drivers. One line per 64 byte chunk. ZENA device not found or not accessible”, that is likely your problem. There is no support for Linux and cannot be used with powerful tools like Wireshark. Now connect the ZENA.

Zena Sniffer Network Configuration Display. There is very little documentation available for the device hardware. See comments near the top of the C file on how to compile and run. Plugging into a Linux box, it was clear that the device was using the USB HID, which was good news for me since it would be simpler to reverse the configuration details.
