hey guyz please help me out, i have an acer aspire 5750G laptop which have broadcom Bluetooth built in but unfortunately it doesn't work. obviously i downloaded the driver from acer website when i try to install it says "Bluetooth hardware did not detected" and i cant find the bluetooth in device manager either. i also opened my laptop to see if the hardware is there and all the lines are connected to the motherboard yap the Bluetooth hardware was there and it was connected to motherboard. my laptop bluetooth is Broadcom [BCM92070MD_REF] i am using windows 8.1
