Detailed Description

Type define for a standard Device Descriptor. This structure uses LUFA-specific element names to make each element's purpose clearer.

See also:

USB_StdDescriptor_Device_t for the version of this type with standard element names.

Note:

Regardless of CPU architecture, these values should be stored as little endian.

Field Documentation

uint8_t USB_Descriptor_Device_t::Class

USB device class.

uint8_t USB_Descriptor_Device_t::Endpoint0Size

Size of the control (address 0) endpoint's bank in bytes.

USB_Descriptor_Header_t USB_Descriptor_Device_t::Header

Descriptor header, including type and size.

uint8_t USB_Descriptor_Device_t::ManufacturerStrIndex

String index for the manufacturer's name. The host will request this string via a separate control request for the string descriptor.

Note:

If no string supplied, use NO_DESCRIPTOR.

uint8_t USB_Descriptor_Device_t::NumberOfConfigurations

Total number of configurations supported by the device.

uint16_t USB_Descriptor_Device_t::ProductID

Unique product ID for the USB product.

uint8_t USB_Descriptor_Device_t::ProductStrIndex

String index for the product name/details.

See also:

ManufacturerStrIndex structure entry.

uint8_t USB_Descriptor_Device_t::Protocol

USB device protocol.

uint16_t USB_Descriptor_Device_t::ReleaseNumber

Product release (version) number.

uint8_t USB_Descriptor_Device_t::SerialNumStrIndex

String index for the product's globally unique hexadecimal serial number, in uppercase Unicode ASCII.

Note:

On some microcontroller models, there is an embedded serial number in the chip which can be used for the device serial number. To use this serial number, set this to USE_INTERNAL_SERIAL. On unsupported devices, this will evaluate to 0 and will cause the host to generate a pseudo-unique value for the device upon insertion.

See also:

ManufacturerStrIndex structure entry.

uint8_t USB_Descriptor_Device_t::SubClass

USB device subclass.

uint16_t USB_Descriptor_Device_t::USBSpecification

BCD of the supported USB specification.

uint16_t USB_Descriptor_Device_t::VendorID

Vendor ID for the USB product.
