I have to communicate to a device which uses serial interface through the USB port. I disabled the Serial Port Login and disabled the Bootup Info. When I list the devices using lsusb, the device is detected. ls /dev/tty* lists a number of tty , but no ttyUSB is listed. There is no change in the list before and after I connect to the device. ttyAMA0 is listed before and after the device is connected. In the window PC the device is detected in COM5. How do I know the port to which it is connected. I have a java application that sends and receive data to the device.
dmesg | grep usb gives [ 3732.485108] usb 1-1.5: Product: ROTOR-GENE
[ 3732.485126] usb 1-1.5: Manufacturer: Silicon Labs [ 3732.485142] usb 1-1.5: SerialNumber: 120876

The device is connected to the USB port though internally the USB interface is connected to a USB-to-UART bridge.For programming purposes this means that the interface appears as (virtual) serial interface (RS232).
