So, there's no movement on my problem. I wrote a request for a problem on the support@uni-trend.com.cn, there has been no answer for several days. Tried reinstalling the application, not helping. Then the device driver flew off and did not put in any way. In the system, the device was defined as UTG900 without drivers. Pitched it to the folder DriverPack_Libusb, says that no driver was found in this folder. When installing Devices Manager Installer.exe, I see that the PL2303_v130 driver is installed (1.3.0?) This already leads to bad thoughts about Chinese clones of PL2303 that are not supported by the official chip manufacturer. Who disassembled the device, what is there with the USB driver?
As a result, I found another computer with Windows 10 on board to check the health of the software. After installation, the program successfully identified the generator and I was able to manage it. As a result, I pulled the driver from this computer and manually installed it on a computer where the driver flew and the software did not work. The device driver was successfully installed, the device is now defined, but the program is still not working.
This led to the idea that the operating system itself does not allow access to the USB port. At the same time, I do not receive any mistakes. I tried to install Devices Manager with Windows Firewall exceptions, but this did not help either.
Guys! Maybe from my confused story someone can understand the reason for what is happening and help me defeat this problem? Friends advise me to clean up the operating system. But I do not want such radical measures yet. At the same time, I will lose the software I installed. And his recovery is both a loss of time and extra nerves. Yes, and I have no confidence that this will help.
