4 Note on SDRPlay RSP1 on Linux

Most distributions will load the msi2500 driver by default that will come in the way of the direct access that SDRangel makes with libmirisdr (and libusb). Thus you will see the SDRPlay in the list of devices and you will be able to select it but it will fail at start time.

Look at dmesg to see if your system has loaded device drivers for the SDR module. They are incompatible with the binary-only driver. Relevant output:

  [20084.148384] msi2500 3-2:1.0: Registered as swradio0
  [20084.148386] msi2500 3-2:1.0: SDR API is still slightly experimental and functionality changes may follow

In this case, edit /etc/modprobe.d/blacklist.conf and add:

  blacklist sdr_msi3101
  blacklist msi001
  blacklist msi2500

Then, unplug the SDRPlay, remove the offending modules and restart the module loading service (or whatever loads the modules on your Linux distribution):

  sudo rmmod msi001 msi2500
  sudo systemctl restart systemd-modules-load.service
