USB Devices and Drivers

USB devices with similar attributes and services are grouped into device classes. Each device class has a corresponding driver. Devices within a class are managed by the same device driver pair. However, the USB specification also allows for vendor-specific devices that are not part of a specific class.

The Human Interface Device (HID) class contains devices that are user-controlled such as the following devices:

• Keyboards

• Mouse devices

• Joysticks

The Communication Device class includes the following devices:

• Modems

• Ethernet adapters

Other device classes include the following classes:

• Audio

• Monitor

• Printer

• Storage Device

Each USB device contains descriptors that reflect the class of the device. A device class specifies how its members should behave in configuration and data transfer. You can obtain additional class information from:
