USB Function Client Drivers (Compact 2013)

3/26/2014

A universal serial bus (USB) function client driver enables a USB device to communicate with a USB host controller. It specifies a single configuration with a single interface for particular client hardware architecture.

Multiple USB function client drivers interface with the same USB function controller driver. This enables one USB function controller on a device to support multiple USB clients performing the same function.

For more information about USB function drivers, see the following topics.

• USB Function Composite Device Drivers
  Act as intermediaries between the USB function controller drivers and one or more USB Function Client Drivers.

• USB Function Controller Drivers
  Offer functions for I/O control codes (IOCTLs), model device drivers (MDDs), and platform dependent drivers (PDDs).

• USB Function Mass Storage Client Drivers
  Expose a storage device, such as a hard disk drive or mass storage device, to a USB host controller.

• USB Function Serial Client Drivers
  Expose a stream interface to serial hardware, such as a serial modem.

For information about adding support for a USB function client driver to your OS, see USB Function Driver Catalog Items and Sysgen Variables.
