Field Name
Length of configuration descriptor in bytes.
Descriptor type.
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.
Device attributes for this configuration.
Bit (7) Reserved. Must be set to 1.
Bit (6) Self-powered. Must be set to 1.
Bit (5) Remote wake-up. Must be set to 0.
Bits (4–0) Reserved. Must be set to 0.
Maximum power consumption for this configuration. Units
used are mA*2 (i.e., 0x31 = 98 mA, 0xF9 = 498 mA). 0x00
reported for self-powered devices.
Note: A value of 0x00 or 0x01 results in the 56-pin package
configuring itself for self-powered mode, whereas a value
greater than 0x01 results in the 56-pin package reporting
itself as bus-powered. This is regardless of what address
0x33 is set to reflect in the 56-pin package.
Length of interface descriptor in bytes.
Descriptor type.
Interface number.
Alternate setting.
Interface class.
Interface protocol.
Index to first interface string. This entry must equal half of
the address value where the string starts or 0x00 if the string
does not exist.
Length of this descriptor in bytes.
Endpoint descriptor type.
This is an Out endpoint, endpoint number 2.
This is a bulk endpoint.
0x0040; High speed 0x0200)
High-speed interval for polling (maximum NAK rate). Set to
zero for full speed.
Reserved for future use. Must be set to zero.
Number of bytes returned in this configuration. This includes
Number of endpoints.
Interface subclass.
