View source for Make USB-Serial devices appear on UI

The list of USB-Serial devices from the ''Serial Port configuration'' page (''Apps'' -> ''Develop Apps'' -> ''Serial Port configuration'') is populated by '''serproxy'''.

serproxy gets the list of devices from '''/proc/tty/driver/usbserial'''. It only gets the devices that have the ''"path:"'', ''"name:"'' and ''"module:"'' properties. If any of these properties are missing, serproxy will ignore the device.

Next, it tries to identify the device. By default, it can only identify 4 devices:
* vendor:0403 product:6001
* vendor:0403 product:6010  // FTDI FT232BM
* vendor:067b product:2303  // PL-2303
* vendor:0856 product:ac33  // B&B Electronics

If the device is not known by serproxy, it looks for it in '''/etc/cmh/serproxy.ports'''.
If it finds it there, serproxy will create a Luup device of type ''urn:micasaverde-org:device:SerialPort:1'', otherwise it will ignore the device.

So, if your USB-Serial device doesn't show up on the ''Serial Port configuration'' page, first make sure it shows up in ''/proc/tty/driver/usbserial'', then add it in ''/etc/cmh/serproxy.ports'' like this:

<code>vendor:06cd product:0121</code>

If the device doesn't appear in ''/proc/tty/driver/usbserial'', follow the instructions on this forum post: http://forum.micasaverde.com/index.php/topic,1471.0.html
