## Detailed Description

USB Device Descriptors, for library use when in USB device mode. Descriptors are special computer-readable structures which the host requests upon device enumeration, to determine the device's capabilities and functions.

## Function Documentation

## § AVRISP_GetDescriptor()

uint16_t AVRISP_GetDescriptor | ( | const uint16_t | wValue,
|  | const uint16_t | wIndex,
|  | const void **const | DescriptorAddress
| ) |  |

This function is called by the library when in device mode, and must be overridden (see library "USB Descriptors" documentation) by the application code so that the address and size of a requested descriptor can be given to the USB library. When the device receives a Get Descriptor request on the control endpoint, this function is called so that the descriptor details can be passed back and the appropriate descriptor sent back to the USB host.

## Variable Documentation

## § AVRISP_ConfigurationDescriptor

const AVRISP_USB_Descriptor_Configuration_t AVRISP_ConfigurationDescriptor

Configuration descriptor structure. This descriptor, located in FLASH memory, describes the usage of the device in one of its supported configurations, including information about any device interfaces and endpoints. The descriptor is read out by the USB host during the enumeration process when selecting a configuration so that the host may correctly communicate with the USB device.

## § AVRISP_DeviceDescriptor

const USB_Descriptor_Device_t AVRISP_DeviceDescriptor

Initial value:
=
{
.Header = {.Size = sizeof(USB_Descriptor_Device_t), .Type = DTYPE_Device},
.USBSpecification = VERSION_BCD(1,1,0),
.Class = USB_CSCP_VendorSpecificClass,
.SubClass = USB_CSCP_NoDeviceSubclass,
.Protocol = USB_CSCP_NoDeviceProtocol,
.Endpoint0Size = FIXED_CONTROL_ENDPOINT_SIZE,
.VendorID = 0x03EB,
.ProductID = 0x2104,
.ReleaseNumber = VERSION_BCD(2,0,0),
.ManufacturerStrIndex = AVRISP_STRING_ID_Manufacturer,
.ProductStrIndex = AVRISP_STRING_ID_Product,
.SerialNumStrIndex = AVRISP_STRING_ID_Serial,
.NumberOfConfigurations = FIXED_NUM_CONFIGURATIONS
}

Device descriptor structure. This descriptor, located in FLASH memory, describes the overall device characteristics, including the supported USB version, control endpoint size and the number of device configurations. The descriptor is read out by the USB host when the enumeration process begins.

## § AVRISP_LanguageString

const USB_Descriptor_String_t AVRISP_LanguageString = USB_STRING_DESCRIPTOR_ARRAY(LANGUAGE_ID_ENG)

Language descriptor structure. This descriptor, located in FLASH memory, is returned when the host requests the string descriptor with index 0 (the first index). It is actually an array of 16-bit integers, which indicate via the language ID table available at USB.org what languages the device supports for its string descriptors.

## § AVRISP_ManufacturerString

const USB_Descriptor_String_t AVRISP_ManufacturerString = USB_STRING_DESCRIPTOR(L"ATMEL")

Manufacturer descriptor string. This is a Unicode string containing the manufacturer's details in human readable form, and is read out upon request by the host when the appropriate string ID is requested, listed in the Device Descriptor.

## § AVRISP_ProductString

const USB_Descriptor_String_t AVRISP_ProductString = USB_STRING_DESCRIPTOR(L"AVRISP mkII")

Product descriptor string. This is a Unicode string containing the product's details in human readable form, and is read out upon request by the host when the appropriate string ID is requested, listed in the Device Descriptor.

## § AVRISP_SerialString

const USB_Descriptor_String_t AVRISP_SerialString

Initial value:
= USB_STRING_DESCRIPTOR(L"000200012345\0"
)

Serial number string. This is a Unicode string containing the device's unique serial number, expressed as a series of uppercase hexadecimal digits.
