I'm guessing you did the same thing i did where you plugged the A619 to your usb port on your computer, which would make sense but you need to pull the micro sd card out of the A619 and have a micro sd card reader that you can then plug into your usb port. The pc suite should then see a device and can then load software etc. 
Hope this helps.

 Plz , I need you help on updating my al619
