I can connect and use Android 3.0+ , 4.0+ devices without any problem and can see and use them from Eclipse as well. 

But, when I try to connect any Froyo/Gingerbread device to my pc, it is not even recognized that any usb device is connected to it. 

I did some research and tried installing driver from own website, installed kies, turned on and off usb debugging, tried connecting as storage,etc but no, nothing is working. It is just being charged when devices are connected. Pc doesn't see any device is connected to it.

My OS is Windows 8.1 - 64bit.

While trying, I've followed these links:
