USB Host Protocol

Hi

I need to send data to a USB device. The serial settings for the FTDI driver of the device are:
Baudrate: 115200
Parity: no
Data bits: 8
Stop bits: 2
Flow Control: RTS/CTS

Does someone know how to implement these settings in the USB Host Library 2.0?

Detailed information of the device and the communication protocol can be found here:
