Field Name
Number of interfaces supported. The CY7C68310 only
supports one interface.
The value to use as an argument to Set Configuration to
select the configuration. This value must be set to 0x02.
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.
Device attributes for this configuration. Configuration
characteristics:
Maximum power consumption for this configuration. Units
used are mA*2 (i.e., 0x31 = 98 mA, 0xF9 = 498 mA).
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 CY7C68310 only
supports one interface.
The value to use as an argument to Set Configuration to
select the configuration. This value must be set to 0x02.
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.
Device attributes for this configuration. Configuration
characteristics:
Maximum power consumption for this configuration. Units
used are mA*2 (i.e., 0x31 = 98 mA, 0xF9 = 498 mA).
Length of interface descriptor in bytes.
Descriptor type.
Interface number.
Alternate settings.
Number of endpoints.
Interface class.
Interface subclass.
Interface protocol.
Index to first interface string. This entry must equal half of
the address value where the string starts or zero if the string
does not exist.
