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. You will find a new file in that directory. It is possible to check if a device is bound to a kernel driver and unbind it in libusb 1. The Python script is available here. With this information, it was straightforward to identify the USB endpoint 0x01 zenq the control channel for setting the channel and USB endpoint 0x81 as the data endpoint for delivering frames.
This is how to “unbind” it: Linux Microchip Zena data, isn’t it beautiful? The Zena sniffer can save a capture in a proprietary file formatand can export selected frames to the clipboard in space-delimited hex bytes.
