This is a LimeSDR Mini.

    I think the complaint is about the fact that auto-discovery of Lime
    doesn't work?  Not sure.
      To me, auto-discovery is fraught with issues, and I have *NEVER*
    in the 17 years I've been
      using Gnu Radio relied on it.
    
    But more disturbing to ME is that the attached screen-cap seems to
    indicate that the Soapy blocks
      are all *device* specific.  This seems wayyyy broken to me.  It
    means you cannot have an application that
      is device agnostic.  We have had device-agnostic apps for a LONG
    time--ever since gr-osmosdr came onto the
      scene and then again when SoapySDR showed up.  We're going back to
    device-specific source blocks?  WHY????

Hail,
    My rtl-sdr soapy source block runs with attached hardware but
running the flow graph with the lime source block throws out the
unpleasant response:

I don't know why the dev_args input of "driver='lime'" is required.

git branch gnuradio 3.9-maint
built with PyBOMBS (on 2021-10-09)
opensuse Leap 15.2.

The web page https://wiki.gnuradio.org/index.php/Soapy was informative
but didn't tell me where to go next with this. Before I begin the
daunting (for a non-developer) task of exploring more deeply, I thought
to query this forum for obvious suggestions or known solution (or bug
status).
