Phidgets Forums

Recently I ordered some devices that have the 231X FTDI chip. When I plug them in I can see the device in the web interface of the SBC.

01 11 FT231X USB UART FTDI 0403:6015 2.00 12

However they do not get attached to a ttyUSB*.

I was using devices with the 231R FTDI chip and they attached to a ttyUSB* with no issues. Will the SBC's work with the 231X FTDI chip? Am I missing something?

The current SBC I am using:

I suspect your device just has an unrecognized VID/PID combination.

Have a look here and see if you can get it to work with modprobe:

If that doesn't work, it may require a newer kernel.

So i did what it said and got this.

usb 1-1.6: Detected FT232RL
usb 1-1.6: Number of endpoints 2
usb 1-1.6: Endpoint 1 MaxPacketSize 64
usb 1-1.6: Endpoint 2 MaxPacketSize 64
usb 1-1.6: Setting MaxPacketSize 64
usb 1-1.6: FTDI USB Serial Device converter now attached to ttyUSB0
usbcore: registered new interface driver ftdi_sio
ftdi_sio: v1.6.0:USB FTDI Serial Converters Driver

It detected it as a different chip, but I was still able to send and receive data. Do think it would be OK to use it like this?

I'm not an expert on FTDI, but if it works, it should be fine.

So it ended up not working for me. I noticed that the drivers here
http://www.ftdichip.com/Drivers/VCP.htm
came out a few years before the 231X chip. Would a newer kernel recognize the chip if the driver is older then the chip or is there another place to get the driver?

It's hard to say.

We do offer a newer kernel for you SBC2 then the one you're running, but it's still pretty old.
