Ufff.. Not, the library USB-Serial don't work with a FT230X, this chips is more inexpensive, that FT232R, but for now, I solve my problem, only change the Product ID using a FT_program, application from FTDI (
www.ftdichip.com), with this you can configure the eepprom of the FTDI chip, I change a Producto ID of my FT230x, I put a Product ID of FT232R, with this change, my Android app work fine, and I can communicate with a serial port of microcontroller PIC16F886 in order to controlling relays and SCRs.
