I have three dongles 2 on one computer and 1 on another I use SDRTrunk and Unitrunker and have never had any issues with ports just installed the drivers and thats it maybe we are doing different things with them
crazy how hard it is to find pictures when you've lost your phone and use too many free cloud storages. eventually this box held 8 nooelec smart v4's used with unitrunker, 3 nooelec smart v4's for sdrtrunk , a raspberryPI & radarBox flight stick for ads-b and a nooelec smasrtee xtr for L-band. ran 24/7 for about two years till I moved
