NAME
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

NAME
usb_dev_descr - USB device descriptor SYNOPSIS
#include <sys/usb/usba.h> INTERFACE LEVEL
Solaris DDI specific (Solaris DDI) DESCRIPTION
The usb_dev_descr_t device descriptor defines device-wide attributes. Please refer to Section 9.6.1 of the USB 2.0 specification. The USB 2.0 specification is available at www.usb.org. The device descriptor is retrieved from a USB device during device enumeration and can be accessed via usb_get_dev_data(9F). A device descriptor contains the following fields: uint8_t bLength Size of this descriptor, in bytes. uint8_t bDescriptorType Set to USB_DESCR_TYPE_DEV. uint16_t bcdUSB USB specification release number supported, in bcd. uint8_t bDeviceClass Class code (see below). uint8_t bDeviceSubClass Subclass code (see USB 2.0 specification of applicable device class for information.) uint8_t bDeviceProtocol Protocol code (see USB 2.0 specification of applicable device class for information.) uint8_t bMaxPacketSize0 Maximum packet size of endpoint 0. uint16_t idVendor vendor ID value. uint16_t idProduct product ID value. uint16_t bcdDevice Device release number in binary coded decimal. uint8_t iManufacturer Index of optional manufacturer description string. Valid if > 0. uint8_t iProduct Index of optional product description string. Valid if > 0. uint8_t iSerialNumber Index of optional serial number string. Valid if > 0. uint8_t bNumConfigurations Number of available configurations. Device descriptors bDeviceClass values: USB_CLASS_PER_INTERFACE Class information is at interface level. USB_CLASS_COMM CDC control device class. USB_CLASS_DIAG Diagnostic device class. USB_CLASS_HUB HUB device class. USB_CLASS_MISC MISC device class. USB_CLASS_VENDOR_SPEC Vendor-specific class. USB_CLASS_WIRELESS Wireless controller device class. ATTRIBUTES
