ZENA Wireless Adapter – MHz MRF89XA
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. 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.
There is very little documentation available for the mifrochip hardware. The packet capture output is sent to standard microcgip.

You will find a new file in that directory. This is how to “unbind” it: Make note of it. Awesome work and thanks for making your tool available as open-source.
Using PyUSB with the excellent Pymissle project by Scott Weston as an example, I quickly put together a tool us can set the channel number and capture frames from the Zena device, dumping the hex bytes to stdout. Zena Sniffer Network Configuration Display. Using the SnoopyPro USB snifferI was able to look ezna 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.
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. 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.
It is possible to check if a device is bound to a kernel driver and unbind it in libusb 1. One line per 64 byte chunk. A number between 11 and 26 is expected.

There is no support for Linux and cannot be used with powerful tools like Wireshark. Newer Post Older Post Home.
Update 20 Feb This will be incorporated in the next release — version 0. Two output formats are supported: Posted by Joe Desbonnet at It comes with free Windows-only software.
I have updated this tool to manage the new hardware version based on the MRF24J40 chip.

You can specify a BMP background as a floorplan and move the nodes to their physical locations as well. You’ll probably need to be logged in as root to do all of these things. I guess we are all spoiled by Wireshark, but I was hoping for more detail and a better UI. Prior to running you need to make sure the ZENA device is “unbound” from any kernel drivers.
Linux Microchip Zena data, isn’t it ush Each chunk is prefixed with a timestamp obtained from the usn computer -v will display version information and quit.
A level of 0 implies no debugging default9 maximum verbosity. I would love to be able to check for this and unbind programatically, but I don’t know how to go about it. Now connect the ZENA. The Python script is available here.
