Can't Read and write from FTDI device












0















I have a device that I am connecting to it successfully from windows application using a D2XX driver,
I am trying to connect to it now from Ubuntu OS ( version 15.04) without success till now.



I installed the D2XX driver.



I did : sudo rmmod ftdi_sio
And : sudo apt-get remove brltty



(sudo rmmod usbserial said there is no device like that)



I also added the function FT_SetVIDPID(0x0403, 0x6014 0 to my code



( I took the numbers from the lsusb command output)



I also set the permission to read and write (666) for the com port /dev/bus/usb/001/???



At last I manages to open the port , could write a command to it but did not get any data back ( the FT_Read function receives 0 bytes after timeout)



In the past I managed to connect to the device from a VirtualBox loaded with Debian.
