Your code would need to hook into the OS so that it receives a message when the device is added or removed from the system. I do not think you can do that directly in Java, but see this white paper.

In java you have to listen the serial port to track the usb. Using javax.comm you can able to read the serial port. You can start from here .

Umm basically I am designing a software for a proximity based radar system. I have made a beta version on vc++ but I am atotal novice in java with almost no knowledge in it. So i need to know about the usb thing, plus how to change into manual and auto modes for doppler and FMCW modes.
