I'm not sure I understood correctly what you mean by this. Please provide a detailed description of what you mean by "it does not work" in a reply on this forum thread, including:
What did you do?
What were the results you expected from doing that thing?
What were the results you observed that did not match your expectations?
Make sure to include the full and exact text of any error or warning messages you might have encountered.
I installed arduino cloud agent on my windows10 pc without problems
I tried to connect several different devices to Arduino cloud: Arduino nano; arduino mega; elego esp-wroom-32 board via usb connection
arduino cloud software does not find device
then i loaded regular arduino ide software to check usb connection. It worked fine and recognized boards showing that usb connection and boards are working properly
tried again several times to connect new device to arduino cloud and message appear that it did not work
opened debug on arduino cloud and it shows when arduino mega is connected to usb port

I'm sorry, but that still isn't enough information for me to be able to provide assistance. I need a detailed description of exactly what you were doing in Arduino Cloud when you encountered this "does not find device" problem. Arduino Cloud has multiple distinct components, and each of those components has multiple distinct user interfaces. Your statement might be referring to any of those things, and the explanation and solution will be different depending on which one you are using when you encountered the problem.
Please provide detailed step-by-step instructions I could follow to reproduce the problem if I was using your Arduino board and computer.
