Error on setup RTL-SDR (Error code -12)

I found this error when i try to setup my RTL-SDR on my PC. I use this same RTL-SDR on a laptop and works properly, indeed, i can use SDRsharp on this same PC and works.

When i try to setup on Matlab Hardware Setup, if fails on search ad connect and that error code -12 is displayed in the command window. I dont know what to do.

Thank you

I found the fix after hours of scouring the Internet!

Install zadig -> Run it as administrator

In Options Check List All Devices >> Uncheck Ignore Hubs or Composite Devices

In drop down menu select the device saying RTL2838UHIDIR >> Click Replace Driver

Voila!

Hi Edwin,

I tried the method you mentioned and it didn't seem to fix my error code -12 issue. Did you happen to come across any other tips? I'm coming up blank right now. I can get my RTL to run using the SDRSharp software, but Matlab doesn't seem to want to communicate with it.
