 Hi Gilles,
I've recently bought a RTL-SDR v3 device as well and believe I've had the same 
problem as you on Win10. It worked on SDR# but wasn't recognized on GNURadio 
3.8.
I can't remember where now, but I found a solution that worked both on the 
RTL-SDR Source and the osmocom Source. It requires you to give an input for the 
"Device Arguments" of "rtl=0" in your source block. Alternatively, also try 
"rtl=1", but mine worked with "rtl=0". Hope it helps!

Best regards,
Gabriel Pinheiro

Hi 
 
 
Which version of GR are you using? 
 
 
If using 3.8.x see here

Hello,
 
Maybe could you help me...
 
I’m using a RTL SDRV3, it works well on my laptop (Win10) with SDRSharp, 
RTL1090 etc.. but GNU Radio Companion doesn't recognized it ? 
 
My GNU Radio flowcharts without using RTL SDR as a source works perfectly.
 
I have some initialization trouble with my RTL SDRV3 on my laptop. The driver 
is ok. It looks Python have some troubles, what do you think about it ?
 My RTL-SDRV3 works on my other computer, here (below) you can see the 
difference with the same flowchart on my laptop. 
  Here when it's working 
  
 
  
and here at start the same but at the end, just "done" and nothing about 
RTL2838 ?!
 

   

 
When I use rtl_test.exe, it seems ok.
 
 
 
Thanks for your help.
 
Best regards.
 
Gil.
