This repository contains a capture of USB communication between a Windows host and a Dynacord CMS 600-3 mixer.
This 8-channel mixer is available in two hardware variants: the new one is USB class-compliant, but the old one uses a [Ploytec]https://www.ploytec.com/) USB audio interface card, and drivers for it are no longer available on modern versions of MacOS nor Apple-chipset Mac hardware like the M1-M4. (See the note here: "drivers not listed are not available")
The Ploytec REVIVAL firmware does not yet support this hardware. The other hope is that a pure software driver like mischa85/snd-xonedb4 may one day add support.
The capture is provided as a .pcap file, captured using USBPCap, on Windows (where there is still a working driver).
The Dynacord CMS 600-3 uses the USB Vendor ID of 0x0562 and Product ID of 0x03eb
