const USB_Descriptor_Configuration_t ConfigurationDescriptor
static

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.

const USB_Descriptor_Device_t DeviceDescriptor
static
Initial value:
= {
.Header = {.Size = sizeof(USB_Descriptor_Device_t), .Type = DTYPE_Device},
.Endpoint0Size = FIXED_CONTROL_ENDPOINT_SIZE,
.VendorID = 0x1fc9,
.ProductID = 0x2045,
.ReleaseNumber = VERSION_BCD(01.00),
.ManufacturerStrIndex = 0x01,
.ProductStrIndex = 0x02,
.SerialNumStrIndex = USE_INTERNAL_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.

const uint8_t LanguageString[]
static
Initial value:

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.

const uint8_t ManufacturerString[]
static
Initial value:
= {
WBVAL('N'),
WBVAL('X'),
WBVAL('P'),
}

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.

const uint8_t ProductString[]
static

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.
