The VDS1022I reporting the same (5, 0, 0) tuple as the HDS200 means the interface-level narrowing approach I proposed doesn't reliably separate the device families. I've posted the analysis and options on the mailing list: https://lore.kernel.org/linux-usb/20260810091322.2201740-1-huangwei@kylinos= .cn/ In short: OWON reuses the same tuples across devices with different userspace needs, so there may be no clean kernel-side fix. The question is now with the USB serial maintainer on how to proceed. --=20 You may reply to this email to add a comment.
