utl: Driver INF - oem37.inf (C:\WINDOWS\System32\DriverStore\FileRepository\ooi_flamenir.inf_amd64_c49d37bc221e3c4a\ooi_flamenir.inf) Make sure you are not selecting the "USB Receiver (Interface 0)" in zadig, and instead are selecting the Bulk in interface, or one that may say RTL2838UHIDIR or something else prefixed with RTL. I get decoding, audio and/or visual spectrum glitches when I set the PPM offset to a non-zero value. At this point I can follow along and flash my devices per whatever instructions my manufacturer/project/boardmaker intends.

First test to make sure that it is not the fault of a bad USB extension cable by plugging the dongle directly into the PC. Try other USB cables if possible. If the USB connector is loose, gently pressing on the top of the USB connector on the RTL-SDR and making a small indentation can help tighten the connection. If it still disconnects often the dongle may be faulty and you should ask for a replacement. Now I can run dfu-util --list again. Note the before and after in the screenshot below. I run dfu-util --list and it finds nothing. I replace the bootloader with the generic WinUSB driver and run dfu-util again and it finds the devices. If you follow the instructions when flashing a device and don't have the right USB driver installed you'll likely get an error like this: Cannot open DFU device 0483:df11 To let you access USB devices, Zadig is a Windows application that installs generic USB drivers like WinUSB, libusb-win32/libusb0.sys, or libusbK. Set the default destination directory for extraction of the driver files (default = "C:\\usb_driver")To see USB devices that already have a driver installed, go to the Options menu and select List All Devices. Extract (unzip) sdrsharp-x86.zip to a folder on your PC. (Important! Many people who have issues forget this step! DO NOT run the files from within the zip file or the following steps will fail). (Also, do not extract into a folder within the Program Files directory, or installation may fail as these folders are often automatically made read only by Windows). Open SDRSharp.exe and set the "Source" to ' RTL-SDR USB'. The source menu is in the top left Hamburger Menu (the three horizontal lines).

Automated Creation/Signing of a Catalog file ( Options → Create a Catalog File / Options → Sign Catalog & Install Autogenerated Certificate):NOTE: When using dfu-util on Windows, I recommend you either be smart about your PATH and add dfu-util, or better yet, make sure the dfu-util.exe and libusb.dlls are local to your firmware so there's no confusion about what libraries are being used. When I run install-rtlsdr.bat a CMD/DOS window flashes on the screen briefly then disappears. Nothing is installed. Zadig is often used to install device drivers for USB-based hardware, such as USB-to-serial adapters and USB-based peripherals. Release your inner bohemian with our Zadig&Voltaire women's clothing. Tops, trousers and leather goods embody a spirit of playful rebellion.
