If your device specifies class and subclass codes to 02, and you want to load another driver instead of Usbser.sys, you have to write an INF that specifies the hardware ID of the device and the driver to install.

In this case, you might have to load your own driver or write an INF that references another in-box driver. If a suitable driver is not found, the device might not have a driver loaded.

If your device belongs to the Communications and CDC Control device class, Usbser.sys is loaded automatically.You do not need to write your own INF to reference the driver. In Windows 10, a new INF, Usbser.inf, has been added to %Systemroot%\Inf that loads Usbser.sys as the function device object (FDO) in the device stack. For the list of USB device class driver included in Windows, see USB device class drivers included in Windows. If they are not installed automatically, contact the device manufacturer.
