Field Name
Length of device descriptor in bytes.
Descriptor type for device descriptor.
USB Specification release number in BCD.
Device class.
Device subclass.
Device protocol.
Maximum USB packet size supported.
Vendor ID.
Product ID.
Device release number in BCD lsb (product release
number).
Device release number in BCD msb (silicon release
number). This field entry is always returned from internal
ROM contents, regardless of the descriptor source.
Index to manufacturer string. This entry must equal half of
the address value where the string starts or 0 if the string
does not exist.
Index to product string. This entry must equal half of the
address value where the string starts or 0 if the string does
not exist.
Index to serial number string. This entry must equal half of
the address value where the string starts or 0 if the string
does not exist. The USB Mass Storage Class Bulk Only
Transport Specification requires a unique serial number.
Number of configurations supported.
Length of device descriptor in bytes.
Descriptor type.
USB specification release number in BCD.
Device class.
Device subclass.
Device protocol.
Maximum USB packet size supported.
Number of configurations supported.
Reserved. Must be set to 0.
Length of Configuration descriptor in bytes.
Descriptor type.
Number of bytes returned in this configuration. This includes
the configuration descriptor plus all the interface and
endpoint descriptors.
