Auvitek AU0828 USB analog/digital TV capture bridge

A USB 2.0 bridge chip from Auvitek used in hybrid analog/digital TV tuner sticks from the late 2000s, most notably the Hauppauge WinTV-HVR-950Q and HVR-850, the DViCO FusionHDTV USB, and the Hauppauge Woodbury. These devices let a PC capture over-the-air ATSC digital TV plus legacy analog NTSC video and VBI data such as closed captions.

recommendation

Worth keeping but flagging as niche legacy hardware. The code was still receiving routine media-subsystem maintenance in 2024, and Hauppauge was still listing the HVR-950Q for sale with Linux support into 2025, so real users remain. That said, USB ATSC tuner sticks are a shrinking category and deployments are low, so it deserves a note that this is a long-tail driver kept primarily for owners of a small set of older Hauppauge and DViCO tuners.

sources

  1. lore.kernel.org

    Upstream activity exists in recent years; au0828-core.c was still being touched by linux-media maintenance work in 2024 rather than removal prep.

  2. docs.kernel.org

    The in-tree documentation identifies the supported AU0828 hardware family as Hauppauge HVR950Q/HVR850, DViCO FusionHDTV USB, and Hauppauge Woodbury USB TV tuner devices.

  3. hauppauge.com

    Hauppauge still listed the WinTV-HVR-950Q for sale on its webstore, indicating at least some new retail availability in/around 2025.

  4. hauppauge.com

    Vendor support material still groups HVR-950Q/HVR-850 as supported products and mentions Linux support for HVR-950Q, consistent with continuing but niche legacy deployment.

codex reasoning notes (technical)

Real driver directory: source inspection via exec_command shows AU0828 USB media/tuner driver code with analog, VBI, and DVB paths. lore_file_timeline on drivers/media/usb/au0828/au0828-core.c yielded the cited lore URL and shows recent maintenance activity, but not evidence of an active removal series. Web search produced the kernel AU0828 card list URL and Hauppauge webstore/support URLs. Assessment: still maintained enough to keep, but annotate as niche legacy TV-capture hardware with low modern deployment.
