In Windows Embedded Compact, you can implement USB function drivers that include mass storage drivers, controller drivers, and serial client drivers.

For more information, see USB Function Drivers.

For more information about how to add or remove catalog items, see Design Your First OS.

Hardware and Software Requirements

The following table describes the catalog items and associated SYSGEN variables you can use to add support for USB function drivers.

Catalog item	SYSGEN variable	Description	Dependencies
Netchip NET2280 USB Function Controller	SYSGEN_USBFN_NET2280	Provides the USB function controller driver for the Netchip NET2280, which contains the Remote Network Driver Interface Specification (RNDIS) interface.	Requires USB function support (SYSGEN_USBFN).
USB Function Support	SYSGEN_USBFN	Provides support for implementing USB function model device driver (MDD)/platform dependent driver (PDD) drivers.	None.
Composite Function Driver	SYSGEN_USBFN_COMPOSITE	Provides support for using multiple USB function drivers concurrently. For more information, see USB Function Composite Device Drivers.	Requires USB function support (SYSGEN_USBFN).
USBFN Mass Storage client	SYSGEN_USBFN_STORAGE	Provides a USB function mass storage client driver to store files accessed by an external device through a USB connection.	Requires USB function support (SYSGEN_USBFN).
USBFN RNDIS Client	SYSGEN_USBFN_ETHERNET	Provides a USB function RNDIS client driver.	Requires USB function support (SYSGEN_USBFN).
USBFN Serial client	SYSGEN_USBFN_SERIAL	Provides a device driver for USB-to-serial, to use USB as a serial port. For example, COM1.	Requires USB function support (SYSGEN_USBFN).Also requires a USB-to-serial adapter.

Only set one of the following SYSGEN variables unless you set SYSGEN_USBFN_COMPOSITE:
