B2C2/Technisat FlexCop USB digital TV receivers

A family of USB 1.1 digital TV tuner sticks built around B2C2's FlexCop II/IIb/III chipset, sold by Technisat as the SkyStar, AirStar, and Cable2PC USB products for receiving DVB-S satellite, DVB-T terrestrial, DVB-C cable, and ATSC broadcasts on a PC. The hardware was common in the mid-2000s and faded out of retail by around 2012-2014.

recommendation

Worth keeping but documenting its niche: the hardware has not been sold new for roughly a decade and Technisat's own support pages stopped updating around 2012-2014, but the kernel code is not abandoned. Hans Verkuil posted a real bug fix for flexcop-usb in June 2024 that was promptly backported to stable, so users with surviving sticks are still served. A note flagging it as legacy hardware would help distros decide whether to keep shipping it.

sources

  1. lore.kernel.org

    Upstream still sees real maintenance: Hans Verkuil posted a driver-specific fix for flexcop-usb in June 2024.

  2. lore.kernel.org

    The 2024 flexcop-usb fix was backported to stable, indicating the driver is still maintained rather than under active removal.

  3. cateee.net

    LKDDb ties this directory to Technisat/B2C2 Air/Sky/Cable2PC USB hardware and identifies it as a USB digital TV receiver driver still present in current kernels.

  4. technisat.com

    TechniSat's SkyStar USB support page shows only old Windows-era downloads from 2012-2013, consistent with legacy rather than current-market hardware.

  5. technisat.com

    TechniSat's AirStar USB support page likewise surfaces legacy downloads, with dated software entries up to 2014.

codex reasoning notes (technical)

Local `rg` on Kconfig/source identified this as the Technisat/B2C2 Air/Sky/Cable2PC USB1.1 FlexCop DVB/ATSC driver. `lore_file_timeline` on drivers/media/usb/b2c2/flexcop-usb.c showed multiple 2024 bug-fix and stable-backport events, with no removal discussion in the sampled recent activity, so removal/deprecate is too aggressive. Web search found LKDDb plus TechniSat legacy support pages whose download dates stop in 2012-2014; that supports hardware obsolescence and low present-day deployment, but ongoing upstream fixes argue for `keep-annotate` rather than deprecate.
