I am using a USB to Serial adapter on my Samsung Nexus phone (Jelly Bean) and it works fine. I use the "Slick USB 2 Serial Terminal" application and the device gets detected and works.
At the moment I write my own example to send and recive messages over RS232 but it's just at the beginning. Up to now the UsbManager detects one USB device if I connect the adapter.
