can't get Lenovo a60+ to appear as an available android device in eclipse

view story

http://stackoverflow.com – Are there any alternative ways to get it to work? Even the adb command of android sdk doesn't detect my phone. Then some said I need to install the phone drivers first, I thought the phone automatically does it when plugged in while usb debugging is enabled, but it appears that it doesn't. http://i.imgur.com/y07i6EZ.jpg?1 I searched for the driver, but was unlucky, it was not included in the memstick that came with the phone. Even the lenovo website doesn't provide it. (HowTos)
