information.
Some customers want to read the serial number
from the ATA or ATAPI device rather than from the
EEPROM. The following flags enable this function
in the firmware:
USE_ATA_DEVICE_SERIAL_NUMBER
For ATA devices, determines if the firmware uses
the serial number reported by the device as the USB
serial number. If TRUE, firmware uses the serial
number reported by the device in response to the
IDENTIFY_DEVICE command. If FALSE, the
firmware sets the USB serial number index to 0 (i.e.
no serial number string is reported in the device
descriptor).
Default Setting: FALSE
USE_ATAPI_DEVICE_SERIAL_NUMBER
For ATAPI devices, determines if the firmware uses
the serial number reported by the device as the USB
serial number. If TRUE, firmware uses the serial
number reported by the device in response to
IDENTIFY_DEVICE command. If FALSE, the
firmware sets the USB serial number index to 0 (i.e.
no serial number string is reported in the device
descriptor). Many ATAPI devices do not report a
unique serial number. It is better to report no serial
number than to report a non-unique serial number.
Default Setting: FALSE
NIBBLE_CONVERT_SERIAL_NUMBER
Determines if the firmware converts each nibble of
the serial number reported by the device into a
single character of the USB serial number. The
Bulk-only mass storage class spec only allows HEX
characters (0-9 and A-F) in the device serial
number. Some devices report other ASCII
characters. Converting each nibble into HEX
assures spec compliance while maintaining the
uniqueness of the serial number.
Default Setting: FALSE
Build Targets
There are two build targets for the CY4611B. They
use exactly the same options for everything except
one item. The CY4611B_AT2LP_PINOUT target

includes the AT2LP_PINOUT.iic when it calls
hex2bix.exe while the
CY4611B_AT2_LEGACY_PINOUT Includes the
AT2_LEGACY_PINOUT.iic configuration file.
