All software required to build and use the device is open source. The firmware
and host tool are a fork of the open-source project ataradov/usb-sniffer.

PID 1209:6688 is used by the USB Sniffer 2 firmware when the device enumerates.

@talpachen can you make it clear which software this PID code goes to inside the PR or on the page? It's not clear what software packages are needed and if all of them are open source.

This PID (0x1209:0x6688) applies to:

• Firmware source code: https://github.com/vllogic/ataradov.usb-sniffer/tree/main/firmware
• Build method: https://github.com/vllogic/ataradov.usb-sniffer/blob/main/firmware/Makefile (built with the open source SDCC compiler)
• License: BSD-3-Clause (fork of the open source project ataradov/usb-sniffer)

Host tool usb_sniffer (same repo, software/ directory) — BSD-3-Clause

The FPGA logic code and the hardware design are also open source; links are above.

@talpachen
Please add the details to the readme linked in the PR, i.e. site: should point to a README where all of this is addressed. Comments in this thread are not retained in tree history.

@cnlohr

Done. The details are now in the README that site points to:

https://github.com/vllogic/dalishen_pi_h7p20/blob/main/hardware/usb_sniffer_2/readme.md

It covers the firmware, host tool, FPGA logic, build toolchain (SDCC) and
licenses (BSD-3-Clause for software/FPGA, GPLv3 for hardware). I also added the
source: field, and site: now points directly at the README. All required
software is open source.

Please take another look.
