Data Translation DT3155 monochrome PCI frame grabber

A monochrome PCI video capture card from Data Translation, sold around the Windows 98/2000 era for industrial imaging, machine vision, and scientific measurement work. It digitises analog video from cameras or microscopes into the host PC, and any remaining deployments are in long-lived lab or factory setups rather than current installations.

recommendation

A candidate for future removal because the underlying card is an early-2000s industrial PCI frame grabber that hasn't been sold new for over two decades and now sees only a thin tail of legacy lab and machine-vision use. Upstream activity on it is limited to passive treewide media API cleanups in 2024 and 2025 rather than any real development, and no in-kernel successor covers the same hardware. It still works, so removal isn't urgent, but it's a reasonable item to flag for eventual retirement once remaining users are identified.

sources

  1. lore.kernel.org

    dt3155 still receives occasional treewide media API maintenance in upstream, including 2024 updates.

  2. lore.kernel.org

    dt3155 was still included in a 2025 cross-driver ioctl conversion series, indicating passive upkeep rather than removal.

  3. manualzz.com

    DT3155 is a Data Translation industrial-accuracy monochrome PCI frame grabber documented alongside Windows 98/NT 4.0/2000/ME-era software, placing mainstream availability in the early-2000s product generation.

codex reasoning notes (technical)

Real driver directory confirmed from local Kconfig/C source via shell (`exec_command`): Data Translation DT3155 frame grabber. Lore evidence came from `lore_file_timeline`; it shows recent touches are sparse and treewide/API-maintenance oriented, and no removal discussion was found before tool budget was exhausted. The Manualzz product manual URL was obtained by web search and indicates an early-2000s Windows-era PCI frame-grabber product, supporting 'not sold new in 2025' and only low legacy/industrial deployments today. No natural in-tree replacement driver covers the same proprietary board; replacement is effectively newer vendor-specific frame-grabber hardware, not a direct upstream driver successor.
