Field Name
Device protocol.
USB packet size supported for default pipe.
Vendor ID. Cypress’s Vendor ID may only be used for evalu-
ation purposes, and not in released products.
Product ID.
Device release number in BCD LSB (product release
number).
Device release number in BCD MSB (silicon release
number).
Index to manufacturer string. This entry must equal half of the
address value where the string starts or 0x00 if the string does
not exist.
Index to product string. This entry must equal half of the
address value where the string starts or 0x00 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 0x00 if the string
does not exist. The USB Mass Storage Class Bulk-Only
Transport Specification requires a unique serial number (in
upper case, hexidecimal characters) for each device.
Number of configurations supported.
Length of device descriptor in bytes.
Type Descriptor type.
USB Specification release number in BCD.
USB Specification release number in BCD.
Device class.
Device subclass.
Device protocol.
USB packet size supported for default pipe.
Number of configurations supported.
Reserved for future use. Must be set to zero.
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.
Number of interfaces supported.
The value to use as an argument to Set Configuration to
select the configuration. This value must be set to 0x01.
Index to the configuration string. This entry must equal half
of the address value where the string starts or 0x00 if the
string does not exist.
