usb_cfg_descr - USB configuration descriptor SYNOPSIS
#include <sys/usb/usba.h> INTERFACE LEVEL
Solaris DDI specific (Solaris DDI) DESCRIPTION
The usb_cfg_descr_t configuration descriptor defines attributes of a configuration. A configuration contains one or more interfaces. A con- figuration descriptor acts as a header for the group of other descriptors describing the subcomponents (for example, interfaces and end- points) of a configuration. Please refer to Section 9.6.3 of the USB 2.0 specification. The USB 2.0 specification is available at www.usb.org. One or more configuration descriptors are retrieved from a USB device during device enumeration. They can be accessed via usb_get_dev_data(9F). A configuration descriptor has the following fields: uint8_t bLength Size of this descriptor in bytes. uint8_t bDescriptorType Set to USB_DESCR_TYPE_CFG. uint16_t wTotalLength Total length of data returned including this and all other descriptors in this configuration. uint8_t bNumInterfaces Number of interfaces in this configuration. uint8_t bConfigurationValue ID of this configuration (1-based). uint8_t iConfiguration Index of optional configuration string. Valid if > 0. uint8_t bmAttributes Configuration characteristics (See below). uint8_t bMaxPower Maximum power consumption, in 2mA units. Configuration descriptors define the following bmAttributes: USB_CFG_ATTR_SELFPWR - Set if config not using bus power. USB_CFG_ATTR_REMOTE_WAKEUP - Set if config supports rem wakeup. ATTRIBUTES

usb_if_descr - USB interface descriptor SYNOPSIS
#include <sys/usb/usba.h> INTERFACE LEVEL
Solaris DDI specific (Solaris DDI) DESCRIPTION
The usb_if_descr_t interface descriptor defines attributes of an interface. A configuration contains one or more interfaces. An interface contains one or more endpoints. Please refer to Section 9.6.5 of the USB 2.0 specification. The USB 2.0 specification is available at www.usb.org. One or more configuration descriptors are retrieved from a USB device during device enumeration. They can be accessed via usb_get_dev_data(9F). A interface descriptor has the following fields: uint8_t bLength Size of this descriptor in bytes. uint8_t bDescriptorType Set to USB_DESCR_TYPE_IF. uint8_t bInterfaceNumber Interface number (0-based). uint8_t bAlternateSetting Alternate setting number for this interface and its endpoints (0-based). uint8_t bNumEndpoints Number of endpoints, excluding endpoint 0. uint8_t bInterfaceClass Interface Class code (see below). uint8_t bInterfaceSubClass Sub class code. (See USB 2.0 specification of applicable interface class for information.) uint8_t bInterfaceProtocol Protocol code. (See USB 2.0 specification of applicable interface class for information.) uint8_t iInterface Index of optional string describing this interface Valid if > 0. Pass to usb_get_string_descr(9F) to retrieve string. USB 2.0 specification interface descriptor bInterfaceClass field values are as follows: USB_CLASS_APP Application-specific interface class USB_CLASS_AUDIO Audio interface class USB_CLASS_CCID Chip/Smartcard interface class USB_CLASS_CDC_CTRL CDC control interface class USB_CLASS_CDC_DATA CDC data interface class USB_CLASS_SECURITY Content security interface class USB_CLASS_DIAG Diagnostic interface class USB_CLASS_HID HID interface class USB_CLASS_HUB HUB interface class USB_CLASS_MASS_STORAGE Mass storage interface class USB_CLASS_PHYSICAL Physical interface class USB_CLASS_PRINTER Printer interface class USB_CLASS_VENDOR_SPEC Vendor-specific interface class USB_CLASS_WIRELESS Wireless interface class ATTRIBUTES
