Why does "Device Universal Serial Parent Device 0" appear in MCGS configuration? Initialization of universal serial parent device failed! "

What version?

Analog operation?

You can find the universal serial parent device 0 in the device window, and the serial parent device 0 corresponds to the serial number 1, that is, COM 1.

If it is running on a computer, then your computer just has no serial port 1 and COM 1. If it is a USB serial port, you can change the serial number to COM 1.

If the serial number of a PC is COMx instead of COM 1, in the device window, change the device number.

If it's running on an embedded MCGS screen ... that's impossible and it won't happen. . .
