[quote]When I plug in my FTDI USB Serial cable, I see:

**[690.149702] usb 1-1.3.2: new full-speed USB device number 7 using msm\_hsic\_host**  
**[690.206805] ftdi\_sio 1-1.3.2:1.0: FTDI USB Serial Device converter detected**  
**[690.219624] usb 1-1.3.2: Detected FT232RL**  
**[690.222615] usb 1-1.3.2: Number of endpoints 2**

**[690.236929] usb 1-1.3.2: Setting MaxPacketSize 64**  
**[690.248588] usb 1-1.3.2: FTDI USB Serial Device converter now attached to ttyUSB0**

But there is no /dev/ttyUSB0

root@swi-mdm9x15:~# ls /dev/ttyUSB0  
ls: /dev/ttyUSB0: No such file or directory  
root@swi-mdm9x15:~# ls /dev/ttyUSB\*  
ls: /dev/ttyUSB\*: No such file or directory

So how do I use it ??
