title: Can`t find ttyUSB[id]
body: <p>I have just started with my Raspberry Pi and I have a project where I want to read data from the USB port. I have installed Java JDK8 and written the program that compiles and run. But I get the message that /dev/ttyUSB1 does not exist.</p>
  
  <p>I just have a cable from the USB port on the Arduino going to the USB port on the RPi and I am using Raspbian Debian Wheezy</p>
  
  <p>When I go to DIR /dev/ and use $ ls, I can only find tty0 up to tty63. I have searched on the internet and some say that you can use ttyAMA0, but this does not work. I have also searched for the same problem, but have not found a answer to my problem.</p>
  
  <p>I have used $ lsusb which gave me 4 devices (001-004) on Bus 001. I can see that, for example, my USB keyboard is listed as Bus 001 Device 004: ID 1532:010b Razer USA, Ltd.
  and if I run $ dmesg | grep Manufacturer I get that:
  [xxxxxxxxx] usb 1-1.2: Manufacturer: Razer</p>
  
  <p>So my question is why does my usb devices not get listed as ttyUSB[id]? Do I have to manually attach it?</p>
  
  <p>I am a bit noob when it comes to Linux.</p>
  
  <p>Hope someone can help me!</p>
