RTL-SDR Blog V4 not working

[swainstm]

I believe release 0.6.0 was supposed to support RTL-SDR Blog V4 dongles. However, sdrtrunk does not seem to recognise my dongle. I am running Windows 11. If I am following youtube instructions correctly, waterfall should start immediately when you start the application?

Dongle works fine in SDR#.

Any ideas on how to troubleshoot and resolve this.

I run like 6 of them on one system.
It's definitely supported. Did you serialize all your dongles before attempting to use them, and did you use ZDiag to install the correct drivers first?

[swainstm]

I only have one. So do I need to serialise them? I did notice somewhere that its serial was 00000001.

Are you using Windows 11?

[funman1steve]

No you don't need to serialize if you only have one but did you use ZDIAG to install the drivers as needed?

Sorry I did not answer that question, but if you mean did I run ZADIG, yes I did. And with this driver and SDR#, the dongle works perfectly in that application. Or is there a ZDIAG that I am missing.

But that driver does not seem to like SDRTrunk for some reason. I found a log file with the following snipit 👎

So sounds like there is some sort of issue with SDRTrunk not liking the driver on my Windows 11 PC?

The details of the driver that is loaded are :
Driver Provider : libwdi
Driver date : 2/06/2012
Driver Version : 6.1.7600.16385
Digital Signer : USB\VID_0BDA&PID_2838&MI_00 (libwdi autogenerated)

The Driver Details :
C:\Windows\system32\DRIVERS\winusb.sys
Provider : Microsoft Corporation
File Versions : 10.0.22621.2504 (WinBuild.160101.0800)

But driver seems to work on other programs, so I assume it is somehow related to something else.

Kept playing around, and seem to have stumbled on the cause of the problem. I have a Dell XPS laptop plugged into a Thunderbolt dock. The RTL-SDRv4 was plugged into a USB port in the dock. However, if use a different USB hub in the device, suddenly it all starts working. So the issue seems to be a combination of SDRTrunk and the dell thunderbolt dock that is causing the issue.

There is no change in drivers with this change, so the driver is the same.

How odd... Glad you got it working :)
