Install Libusb Windows 10
Zadig is a Windows application that installs generic USB drivers, such as WinUSB, libusb-win32/libusb0.sys or libusbK, to help you access USB devices.
Just to add a little bit here. DJI has not properly signed drivers with Windows yet. Having to pay a lot to get drivers signed of course sucks. I haven't read full page you link to and don't know if prices are mentioned. Noti dlya fortepiano pesni ani lorak. But some cost is probably good to prevent MS getting 'spammed' with unnecessary requests. However what's worry me is the 'may still refuse to sign the driver' part.
If MS refuses to sign a driver, there's probably a good reason. Possible I guess reasons could include the driver makes the OS unstable, or the driver are doing something it is not allowed to do. Considering all the accusations of DJI/China spying on us, it would probably be a good sign to DJI's customers if drivers were signed (Besides getting rid of the added trouble of installing of course).
