Reply to unboxed vci 100se

hey everyone, i unboxed the vci 100se yesterday and i was extremely excited to start using it. but when i plugged it into my one week old 13'' macbook pro, none of the lights even turned on..): then i tried it again and a message popped out saying that "one or more usb devices was taking up too much power and the usb port was disabled". i tried it then with a power supply but my vci still wont even turn on.. i have never even seen its lights turn on; i tried this on my windows hp laptop but the device still wont turn on..
someone please help!
