I am in the process of breadboarding an Arduino for a project and am using my FTDI Serial cable Adafruit FTDI Cable (tested working on Windows 7). I have also tested the breadboarded Arduino successfully on Win7.
When I plug the FTDI Serial cable into my Linux (Ubuntu 14.04 with Mint Desktop) laptop and the other end to my project (exactly as I did for Windows and it works for Win7), the Tools, Port is grayed out when in Linux.
I have tried running Arduino as root, with no success.
The output of : dmesg | tail is
sudo dmesg | tail [ 729.069015] usb 4-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 729.069019] usb 4-1.2: Product: TTL232R-3V3 [ 729.069022] usb 4-1.2: Manufacturer: FTDI [ 729.069024] usb 4-1.2: SerialNumber: FTF50VXW [ 729.487689] usb 4-1.2: USB disconnect, device number 4 [ 729.615330] usbcore: registered new interface driver usbserial [ 729.615384] usbcore: registered new interface driver usbserial_generic [ 729.615432] usbserial: USB Serial support registered for generic [ 729.621997] usbcore: registered new interface driver ftdi_sio [ 729.622057] usbserial: USB Serial support registered for FTDI USB Serial Device
When I type "lsusb" into the terminal, there is no difference between when the FTDI is plugged in and not plugged in. I have tried switching ports with no success.
