title: Mount USB device on router - OpenWrt
body: <p>I am new to OpenWrt and Linux/Unix shell. Prior to this, was using dd-wrt for 2 years. Recently switched to OpenWrt and got the basic setup done(wifi/internet working). I need to install transmission my router. But, USB device won't mount.</p>
  
  <p>The Details of the router are as follows:</p>
  
  <p><strong>Router Model:</strong>
  Asus RT-N13U B1</p>
  
  <p><strong>Image flashed:</strong>
  chaos_calmer 15.05.1 (openwrt-15.05.1-ramips-rt305x-rt-n13u-squashfs-sysupgrade.bin)</p>
  
  <p><strong>Usb Details:</strong>
  Crusier Blade 16GB usb 2.0
  Formatted to ext4 using GParted bootable cd</p>
  
  <p><strong>Drivers Installed:</strong></p>
  
  <ul>
  <li>kmod-usb-core(preinstalled)</li>
  <li>kmod-usb-dwc2(preinstalled)</li>
  <li>kmod-usb2</li>
  <li>kmod-usb-storage</li>
  <li>kmod-fs-ext4</li>
  <li>kmod-scsi-core(preinstalled)</li>
  </ul>
  
  <p>Here are permissions for dev/sda, /dev/sda1 and /mnt (set 777 manually):</p>
  
  <pre><code>~#ls -l /dev
  brwxrwxrwx    1 root     root        8,   0 Jan 17 21:56 sda
  brwxrwxrwx    1 root     root        8,   1 Jan 17 21:56 sda1
  
  ~#ls -l ..
  drwxrwxrwx    2 root     root             0 Jan 16 21:28 mnt
  </code></pre>
  
  <p>Error while mounting:</p>
  
  <pre><code>~# mount -t ext4 /dev/sda1 /mnt
  mount: mounting /dev/sda1 on /mnt failed: No such file or directory
  
  echo $?
  255
  </code></pre>
  
  <p>sda1 is present inside dev and /mnt directory exists. Still it shows an error.</p>
  
  <p>I have tried installing/reinstalling and then mounting, but for the same result. Also when I disconnect the USB <strong>sda</strong> and <strong>sda1</strong> folders disappear and then reappear when USB is reconnected so I guess the device is being detected successfully.</p>
  
  <p>What is it, that I am missing?</p>

  <p><strong>Edit 2:</strong>
  Switched to LEDE 17. Is more stable and have had zero issues in the past week.</p>
