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.
