HID: Human Interface Device Class

This handles host side control of devices such as keyboards, joysticks, mice, pointers, buttons, sliders and devices that might be used to interact with the ‘real world’. It can also be used with devices that provide data in a similar fashion, such as point-of-sale equipment.

Hub: External Hub

HCC’s host controller ports all contain root hubs and port managers as standard. The HUB class driver supports the connection of one or more external USB hubs to the system.

MST: Mass Storage

This is used in conjunction with HCC’s extensive range of file systems to enable host side file access for thumb-drives and other USB media.

CDC-ACM: CDC Abstract Control Model

This provides a serial interface to devices such as modems.

CDC-ECM: CDC Ethernet Control Model

This presents a USB device to the system as a Network Adaptor.

CDC-EEM: CDC Ethernet Emulation Module

This sends and receives Ethernet frames over USB.

CDC-OBEX: For OBEX devices

This creates a virtual com port over USB. OBEX stands for Object Exchange.

CDC-FTDI: For FTDI USB serial devices

This builds an interface to an FTDI serial interface.

AUDIO: Audio Class Driver

This uses full Isochronous transfer to provide continuous periodic data transfer required to support real-time streaming audio. This ensures that audio data can be supplied in real-time to support media, entertainment and other digital audio devices.

MIDI: Midi Class Driver

This provides an easy way to interface with a wide range of USB-MIDI devices over USB.

MTP: Media Transfer Protocol

This is used to transfer audio, pictures and similar digital media files. Uses object based data exchange between host and device and can be used to handle control commands remotely.

PCL: Printer Class Driver

Host side USB Printer Class Driver to a printer. Using HCC’s PCL5 utility, a document can be generated in RAM and can then be sent by the Class Driver to a printer.
