if i remember correctly to get sleep using the docking station it required to generate a USB ports kext while the docking station is connected then always using that port for the docking station since the path would change if you use a different USB port. herve had a thread on docking stations but that might have been for the old E-series not the USB docking station. for BT if it shows in your usb bus then it needs a driver or firmware uploader.
