I have a smart card reader called SK-284. It support two communication methods, RS232 and USB.
In my case only USB is enable. When I connect this device to my Linux laptop, via USB, It wont get detected. I run '$dmesg' command to check on which ttyUSB port it get detected, I got following output,

My laptop specification:
OS: Ubuntu 12.04
Kernel: 3.2.0-54-generic-pae
When I connect same device to Windows 7 and run device manager, It got detected under Human Interface Device (HID). and some test applications are running fine.
My task is to write a small code on Linux to detect the smart card by device.
So where do I get to know on which ttyUSB port is used by this device, or any other method to get connected to this device.
Thanks in advance.
