Tinker Board Forum

Hi,
I installed the D2XX shared library(Version 1.4.8 ARMv7) from ftdichip.com website on my tinkerboard. 
when i try to list devices an Error appear:
FT_Open(0) failed.
I also try to Unload ftdi_sio from lsmod, but there is no ftdi_sio in lsmod!
I tested D2XX library(Version 1.4.8 ARMv6) on raspi successfully.( when checking lsmod there is ftdi_sio and after unloading it the ftdi driver works correctly)
what's wrong?!
Thanks.

I suspect that the library don't fit well with TB. What for are wanting the ftdi_sio ?

The function FT_ListDevices() from DT2xx driver works, and i can get the connected device serial number. But when i try to open the device, it fails!

In ftdi website for using D2xx driver mentioned that ftdio_sio and usbserial modules must unload to open device successfully. the command is rmmod ftdi_sio. when i try to unload these modules, this error appear: "Module ftdi_sio is builtin".
In raspi when use (sudo lsmod) a list apear which consist of ftdi_sio and usbserial. When use sudo lsmod in tinker board there is only one Module (8723bs) and nothing else to unload!

Please do not open duplicate topic thread or else.
Thank you.
