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.

Bit 6 Self powered. See
value
Bit 5 Remote wakeup. 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). The
value entered here is only used by the 56-pin packages and
affect the reported value of bit 6 of address 0x33 in that case.
