Yes, I'm using VMWare and lsusb doesn't seem to find the Airspys: 7.PNG Earlier, I saw both Airspys in a VMWare setting called Removable Devices, but now they're not showing up anymore. trunktracker@tampabay.rr.com From: op25-dev@yahoogroups.com [mailto:op25-dev@yahoogroups.com] Sent: Saturday, November 24, 2018 10:17 PM To: op25-dev@yahoogroups.com; 'Trunk Tracker' Subject: RE: [op25-dev] Re: Beginner's Guide To Setting Up OP25 From Scratch Does "lsusb" see your AirSpy device? You have lots of errors in your output but the FATAL: Failed to open AirSpy device (-5) AIRSPY_ERROR_NOT_FOUND seems like the first one to solve and it may solve the rest. You're doing this under VMWare, correct? Is VMWare making the USB device available to your virtual machine? -- Apu
