DSDPlus RTL V4 Error -5

[vince48]

Greetings
I'm trying to use my new RTL V4 dongles with DSD+ (Fastlane) and I keep getting "device is in use" I have no other dongle open.

When I run RTL 32bit program I get this while reading the eeprom.exe

rtl-sdr-32bit-20240707>rtl_eeprom.exe
Found 1 device(s):
0: Generic RTL2832U OEM

Using device 0: Generic RTL2832U OEM
usb_open error -5
Failed to open rtlsdr device #0.

What am I doing wrong?

Make sure all other programs are closed, if it persists pull/plug the dongle... dsdplusfastlane...what are you running, in what order?

 

[vince48]

everything is closed
pulled out V4 then re-inserted

1.a bat then FMp24

still no joy, same error,

For the rtl-sdr-blog v4 I had to run zadig specifically for the v4 (you only need to do this once for blog v3 and nooelecs, and once for blog v4)

If you've done that already, you'll need to download the basefiles, run dsdplus.exe, in the dsd+ 1R event window, go to Misc/download newest base files..
It will download to your dsdplusfastlane folder, extract it, open the dsdplusbasefiles folder, in it open the dlls folder, copy the rtlsdr_V4.dll and paste it into you dsdplusfastlane folder

Might want to check Windows Defender is not blocking the link between fmp24 and dsd+. I think I had to allow an exception in Windows Defender.

I have the latest base files, I did that first since its ben written the newest base file has the rtl.dll to run rtl V4

in zadig, which driver do I use?

no, I didn't get any notices from Defender when trying to run DSD+ nor trying to open the V4

Problems like this are usually caused by installing the USB driver for the wrong device.
Unplug all dongles, then use Device Manager to delete them.
Plug in a dongle and then do the following:

Run Zadig.

Under Options,
make sure to select "List All Devices"

and unselect "Ignore Hubs or Composite Parents".

Then choose the dongle's Composite Parent and install the driver.
