Error probing device: no available RSP devices found

[suhr]

Describe the bug

Soapy SDR can't find MSi.SDR even though sdrplayApi is active.

Steps To Reproduce

Steps to reproduce the behavior:

1. Enable services.sdrplayApi.enable
2. Overlay soapysdr-with-plugins as described in the documentation
3. Run SoapySDRUtil --probe="driver=sdrplay"

Expected behavior

SoapySDR should find the device.

Additional context

The USB device is available:

/home/suhr> lsusb -d 1df7:                                                                                                                                                                                                                 09/08/2023 12:46:00
Bus 005 Device 002: ID 1df7:2500 SDRplay RSP1

And sdrplayApi is active:

/home/suhr> journalctl -b --unit=sdrplayApi                                                                                                                                                                                                09/08/2023 12:46:23

This issue can be fixed by adding the following line to the system configuration:

boot.blacklistedKernelModules = [ "sdr_msi3101" "msi001" "msi2500" ];

[zaninime]

Which board do you have? I can't reproduce on my setup. I didn't need to black list anything manually, but I'm running on RPi4 so those modules might not have been even compiled for the kernel I'm running.
