Zena Sniffer Network Configuration Display. It is possible to check if a device is bound to a kernel driver and unbind it in libusb 1. On Ubuntu you can do sudo bash to avoid prefixing everything with “sudo”. Linux Microchip Zena data, isn’t it beautiful? The Zena sniffer can save a capture in a proprietary file format , and can export selected frames to the clipboard in space-delimited hex bytes. 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. With no Linux support, I decided to write my own user space Linux driver to capture packets with the goal of integrating it into libpcap captures and other tools including Kismet Newcore.

There is very little hsb available for the device hardware. There is no support for Linux and cannot be used with powerful tools like Wireshark.

Skip to secondary content. This is how to “unbind” it: Awesome work and thanks for making your tool available as open-source.


A number between 11 and 26 is expected. Prior to running you need to make zea the ZENA device is “unbound” from any kernel drivers.

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

A level of 0 implies no debugging default9 maximum verbosity. I have updated this tool to manage the new hardware version based on the MRF24J40 chip.

In this post I’ve documented reverse engineering efforts by myself and others and micrichip a small C utility for pcap packet capture on the Zema platform. You’ll probably need to be logged in as root to do all of these things.

You will find a new file in that directory. On Ubuntu you can do sudo bash to avoid prefixing everything with “sudo”. Two output formats are supported: Now connect the ZENA.

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.
