SDRTrunk Prevent SDRTrunk from trying to use multiple dongles

[danko139]

Is there a way to "blacklist" a dongle so SDRTrunk (v0.5.0-alpha6) doesn't steal it away from another app already using it?

My experience has been (Windows 10 Professional) that SDRTrunk sees all dongles plugged into USB ports and will try and use them all, which is a nice feature. However, as soon as I run SDRTrunk, my Unitrunker and/or Dump90 processes crash because SDRTrunk has grabbed the dongle from them.

So is there a config file or .json file I can edit to have SDRTrunk use only my Airspy Mini-R2 and leave the other RTL-SDR dongles alone?

I found lots of threads and getting SDRTrunk to use multiple dongles, but my search turned up nothing about my situation. Absolutely love SDRTrunk.

I may have figured something out. One Windows 10 machine where this "grabbing" behavior does NOT occur, the Airspy Mini is and the RTL-SDR dongles are listed in Device Manager under "Universal Serial Bus devices" while on the failing system only the Airspy is listed under "Universal Serial Bus devices" while the RTL-SDR is listed under "libusbK USB Devices" higher up in the Device Manager list. So it may simply be a driver issue. I will delete the RTL-SDR devices and re-add them with Zadig and see if that was causing this behavior.

Problem solved. Reinstalled the RTL-SDR dongle drivers with Zadig 2.5 and things work fine now. SDRTrunk no longer adds the RTL-SDRs to its list of available tuners and everyone is happy.
