5.2 VID/PID/SN and Strings format
The default USB vendor ID, product ID and the strings for vendor name and product
name can be changed by storing customized values into the flash. The serial number
(defined in mass storage device class) can also be customized. It should be noted that
the VID and PID values cannot be set to 0x0000 or 0xFFFF. The default vendor string
of the SN11088 is “USB NAND”. The default product string is “FLASH DISK”.
Therefore, the Windows will show “USB NAND FLASH DISK” when the default
string is used.
Upon power up, if the flash doesn’t have vendor VID/PID stored, default USB vendor
ID (hex 0C45) and product ID (hex 1060) are returned to the host. The
VID/PID/Serial number and vendor/product strings can be programmed through the
mass production software provided by Sonix.
The serial number format in the Mass Storage Class device descriptor is described in
section 5.1.1.1 of the spec. If the manufacturers needs to have serial number, then the
value of the highest two nibbles (nibble 1 and 2) of the serial number can not be 0xFF,
or the serial number feature will be disabled.
