To be able to use RTL USB sticks, the dll files
must be added to the SDR-Console folder; they're not distributed with the installer natively. SDR-Console can't see the RTL stick unless those dll files are in place - it can see RTL sticks over TCP, but not USB connected ones. So while it natively supports SDRplay and many other devices, the nature of the RTL USB dll files (they're not technically drivers, that's what the Zadig drivers are for, the dll files allow SDR-Console to communicate with the Zadig drivers which pass the info to and from the RTL hardware).
I've tried this several times so far (alongside my long running v2 installation) and while v2 works with the exact same hardware without change, v3 still just crashes upon trying to start the RTL stick. I sent off the bug tracker dump file and a screenshot to Simon, I'm sure he'll look over it whenever he's got the opportunity. It could just be an issue with some changes in v3 that might require updated RTL dll files compiled to make use of that version, I don't know but sooner or later there'll be a solution I'm sure.
On your installation, if you open up the Definitions for what's supported, you'll see RTL SDR (TCP) but not RTL SDR (USB) which is what I require as pictured:
If it ends up working, great, if not v2 is still very useful to me as well. I never got into the LW/SW side of monitoring, was never an interest of mine and I know SDR-Console really is fantastic for that purpose but I'm still basically a 25 MHz and above kinda guy.
