FTDI default VID (hex)
FTDI default PID (hex)
A unique serial number is generated and programmed
into the EEPROM during device final test.
Enabling this option will make the device pull down
on the UART interface lines when in USB suspend
mode (PWREN# is high).
Returns USB 2.0 device description to the host.
Note: The device is a USB 2.0 Full Speed device
(12Mb/s) as opposed to a USB 2.0 Hi-Speed device
(480Mb/s).
Taking RI# low will wake up the USB host controller
from suspend in approximately 20 ms.
Enables the high drive level on the UART and ACBUS
I/O pins.
Makes the device load the VCP driver interface for the
device.
