I will have to disagree. While not the optimal solution to this problem, AirNav should have had a driver ready for the product, this isn't a Windows problem. I suggest that this is an issue with Zadig and its inability to install the driver or the copy of the WinUSB driver on your system. You proved this by not being able to utilize 3 different DVB-T type dongles, all that rely on the WinUSB generic driver. Windows is installing the driver for the chipset it sees, the Realtek 2832U chip. The drivers that everyone uses for SDR, in our case for ADS-B, is not exactly what the chip was designed to do. Windows installs the Realtek drivers, we are trying to substitute a generic driver in its place. If that driver is failing to load, then blame the driver.
