Configuration
Item Name
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. See
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.
See

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.
