Can SDR# be configured to support I/Q data via USB from the CommRadio CR1a?

(Apologies if duplicate post - Submitted several days ago w/o, AFAIK, Topic appearing or Moderator notice of issue...)

If it's listed with the available sources, then it's supported. If it's not, it's not supported.

If not listed as "built-in" supported input source, can a "custom" IQ input be added as a plug-in?

Yes, and someone has to pay for it.

Given that there are ZERO standards for how SDRs "do USB", it's not clear how this would work in practice.  Someone would still
  have to write a driver that interfaces between the radio and this "generic" input into SDR#.

In the audio world, there is such a thing as a "class" driver interface.  Every USB audio interface conforms to a standard way of
  interfacing to it, so that you don't need a special driver for each manufacturers USB audio device, and applications software can
  generally blissfully unaware.  Such is NOT true for SDR devices.

I believe Soapy SDR is such an effort as is ExtIO. Neither is a perfect solution.

Could the CR1a USB output be "converted" (via some type of cable adapter) to provide the IQ data as SDR# soundcard input?

Have you got this radio?
The manual says there is software to support it.
It looks as if it sends data via a COM port, if so your choices are minimal.

Works but is very limited - Was hoping to find software alternative

Yes, that's what I thought.
I've seen an Elad which has similar with a Bluetooth to Android adaptor. [The Elad also has a proper USB IQ output]
It seems to me the limit is in the serial data stream.

Maybe the better way is an IF tap so more data is output?
