So, i am using a development board with a C8051F388.
the problem is, i was trying to use the serial port via USB to connect to PC, and use a terminal to see what it was outputting, but when i try to choose the COM port, it does not show that i connected
Every time i plug it to PC it shows a windows message
and when i go to the Device Manager it show that the device was not recognized
it is in PT. is says "Unknown USB device" and in Properties shows a error called (code 43)
the board uses a FT230XS-R FTDI driver. I already installed all drivers but still cant solve the problem.
p.s. at moment the board is only using the USB plug to use the serial port. the power and flashing is handled by a USB Debug adapter.

In my case, software using a COM port (USB VCOM) to communicate with our custom prototype worked on Windows 10 (auto-install/mapping of drivers when the prototype was first connected to the PC), but not for lab PCs running Windows 7. So, direct experience with the use of a custom INF file. There might be another solution that works more automagically, but I'm not aware of it. The OP says "development board," but it's not clear if that's a Silicon Labs board, or a custom board built around the C8051.
For a software example, the NXP LPC54S018M SDK has a sample USB VCOM project that includes a suitable driver INF skeleton and a nice README that explains the steps to modify the file for your specific VID/PID.

Indeed.
