Device attributes for this configuration.
Bit Descriptions
7 Reserved. Must be set to 1.
6 Self-powered. Must be set to 1.
5 Remote wake-up. Must be set to 0.
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.
Length of interface descriptor in bytes.
Descriptor type.
Interface number.
Alternate setting.
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 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.
Max data transfer size.
HS interval for polling (max NAK rate).
Length of this descriptor in bytes.
Endpoint descriptor type.
This is an In endpoint, endpoint number 8.
This is a bulk endpoint.
Max data transfer size.
HS interval for polling (max NAK rate).
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.
