I have the file but it looks that is missing a license based on the website:
DJI RC FCC | Dji Rc Fcc you need a PASS.TXT that is missing on mine may best guess is that the pass text file is the license file that it should be embedded in the .exe file or the dll but I don't have a good decompiler to analyze the code nor I am a developer, if if there is any of you out there willing to give it a try send me your email and I will send you the files. Also based on the cements also it could be that you have to send him your DJI RC S/N so he can cook it in the EXE that connects to his server. Happy Ester Hunting...
This is the only info I have been able to extract from the libusb0.dll with Resource Hacker... I think without a proper decompiler I am stuck
