ABWB Wifi & Bluetooth Card keeps preventing sleep :(

Hey guys I purchased this ABWB Wifi & Bluetooth Card that contains a genuine Apple BCM943602CS Card. The card uses a PCIE Slot on the Mobo along with a USB Cable that connects to the USB Header on the Mobo. Both Wifi and Bluetooth work, but when I try to sleep the system, it immediately wakes itself..... Sleep was working normal before I connected the USB part of the card, which I'm aware is for the BT.

Any ideas how I fix this problem?

This is what I bought.....
