Can you provide your conf file? What hardware are you using? It's possible you're overloading the USB bus, are you connecting them to a USB 3.0 hub?

my conf file is FULL of channels - which i wouldn't want to post here -

but the config i know is good, with just 3 AirSpys its good, with the 4th one its giving an issue
and if i disable the 3rd one, the 4th one will run fine.. so its an issue when i have 4 Active at a time

all my dongles on this PC im using all 4 AirSpy Mini's
plugged into the computer directly, no SUB Hubs

how do i check if the USB is being overloaded?

There are configuration parameters beyond the specific channels / frequencies / names that may be important for debugging. Can you strip the channel specifics from the config file and share that?

I would suggest playing with the bandwidth and / or the output format to see if you can get all 4 running at the same time. 6000000 samples per second x 16 bit samples x 2 for complex readings x 4 dongles = a lot of data.

usbtop is a utility that will show how much USB bandwidth is being used, running that while stepping through 1-4 active dongles may be informative.

I would recommend splitting your config into 4 pieces, one config file per dongle, and run multiple instances of rtl-airband simultaneously. If you can run 4 independent instances of rtl_airband, each with their own dongle but you can't run one instance with 4 dongles then the next step would be to look at rtl_airband. If on the other hand you can't get 4 independent instances running, then the next step would be to look at the OS, USB bus, hardware, etc.

After removing my Channels, here is the config file

FYI with the channels still in the config, this will run, as the last dongle was disabled,

fft_size = 2048;
localtime = true;
log_scan_activity = true;
multiple_demod_threads = true;
devices: (
  {
    #disable = true;
    type = "soapysdr";
    device_string = "driver=airspy,serial=0xF8A868FF29679947";
    gain = "LNA=5,MIX=5,VGA=15";
    sample_rate = 6.0;
    centerfreq = 153.000;
    channels:
    (
      #Channels Go Here
    );
  },
  {
    #disable = true;
    type = "soapysdr";
    device_string = "driver=airspy,serial=0x62CC68FF21865317";
    gain = "LNA=5,MIX=5,VGA=15";
    sample_rate = 6.0;
    centerfreq = 157.200;
    channels:
    (
        #Channels Go Here
    );
  },
  {
    #disable = true;
    type = "soapysdr";
    device_string = "driver=airspy,serial=0x744C60C8214D6E4F";
    gain = "LNA=5,MIX=5,VGA=15";
    sample_rate = 6.0;
    centerfreq = 461.500;
    channels:
    (
      #Channels Go Here
    );
  },
  {
    disable = true;
    type = "soapysdr";
    device_string = "driver=airspy,serial=0x744C60C8214D6E4F";
    gain = "LNA=5,MIX=5,VGA=15";
    sample_rate = 6.0;
    centerfreq = 453.500;
    channels:
    (
      #Channels Go Here
    );
  }
);

here is a "sample" of what my Channels configuration look like

{
        #disable = true;
        freq = 151.0125;
        lowpass = 3200;
        highpass = 200;
        bandwidth = 5000;
        modulation = "nfm";
        notch = 146.2;
        ctcss = 146.2;
        outputs: (
          {
            #disable = true;
            type = "file";
            directory = "/path/torecordings/Channel1";
            filename_template = "Channel1";
            split_on_transmission = true;
            include_freq = true;
          }
        );
      }

finally installed usbtop

as I just revisited this issue, and i still get errors of

so here is my usbtop output

i just tried changing 2 of the AirSpy's to 3.0 Sample Rate instead of 6.0, and i was still getting the same behavior
