How to install FTDI drivers on Colibri T30


We have a USB device required to run on Colibri T30 (flashed with latest image Linux colibri-t30 3.1.10-2.8.6+g37b9f033652b #1 SMP PREEMPT Mon Apr 1 13:13:50 UTC 2019 armv7l GNU/Linux ).

But it looks like the FTDI drivers are missing - usb-devices for that particular device displays:

Bus=02 Lev=02 Prnt=02 Port=02 Cnt=01 Dev#= 3 Spd=12 MxCh= 0

Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1

Vendor=0403 ProdID=6001 Rev=06.00


Product=FT232R USB UART


Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=90mA

If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)

Typing modprobe ftdi_sioreturns an error:

modprobe: ERROR: could not insert ‘ftdi_sio’: Exec format error

Downloading the ftdi libraries (libftd2xx-arm-v7-hf-1.4.8.gz) from and installing them as per their instructions didn’t help

Any suggestions?

Or is there another image for ColibriT30 that has support for FTDI devices with drivers already installed?

Kind regards…

HI @choco

Thanks for writing to the Toradex Community!

In the default kernel, the driver for FTDI is not enabled, you need to compile a custom kernel by following the instructions on this site and the following configs enabled:


Best regards,

Thanks for the link with instructions for compiling the kernel. I will let you know how it goes.

Where would one need to go to set up the configs you mentioned earlier ( CONFIG_USB_SERIAL_FTDI_SIO and CONFIG_USB_FTDI_ELAN)?

I have enabled USB FTDI Single Port Serial Driver after running make nconfig:

Kind regards.


I have enabled USB FTDI Single Port Serial Driver after running make nconfig.

That’s correct. If you create a custom kernel, then don’t forget to deploy the kernel modules too.

Best regards,


I have compiled a custom kernel with FTDI Single Port Serial Driver builtin (also added the USB debug option that came in handy). I have also enabled Elan U132 Adapter Host Controller and Elan PCMCIA CardBus Adapter USB Client due to their dependency.

I had to run insmod ftdi_elan first, followed by insmod ftdi_sio in order for the Bluetooth device to be mounted in /dev/ttyUSB0, as required by our software.

Thank you for your help.

Kind regards.

Perfect that it works. Thanks for the feedback.

Best regards,
