title: How do I connect Arduino nano with QinHeng Electronics HL-340 USB Serial Adaptor to OpenWrt?
body: <p>When I connect the USB interface from my arduino nano to my openwrt router then the command <code>lsusb</code> shows:</p>
  
  <pre><code>Bus 001 Device 003: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter
  </code></pre>
  
  <p>But I do not get a new serial device in <code>/dev/tty*</code></p>
  
  <p>I have <code>kmod-usb-serial</code> installed.</p>
