In general, you cannot use a single INF file that differentiates between device installations that are based on the operating system version. For example, if the files or registry settings that support a device differ between versions of x64-based operating systems, you must create an operating system-specific INF file for each version.
Ok, I understood.
In the folder "lpcopen_examples_windows_usb_drivers_v1.20" there are 4 files :
So, each file correspond to an operating system version, because there are no a lot of information in each file about the version.
Just use "lpc-ucom-vcom", the other are for different USB classes. usbser.sys should be provided by Microsoft. There are plenty of info. on "how to install VCOM driver manually from Windows" online.
