AC7260 bluetooth code 43 possible cause?


I noticed the following on my Samsung 730U3E laptop:

When the bluetooth driver is still trying to load, under USB Controllers -> Generic USB hub (there is 2 on my laptop) -> Power, it will show the bluetooth device.

Under that, it shows my usb hub have 500mA available.

For the AC 7260 bluetooth, it will show it uses 100mA. I've also a realtek usb card reader on the same usb hub that uses 500mA.

I suspect this could be the cause that prevent the bluetooth to load with a code 43.

When I switch back to my original intel 6325, the bluetooth will show it uses 0mA.

I'm running Window 8.1 64 bit with the latest Intel drivers.

I'm not sure if this is the cause. It is possible to make the bluetooth on AC7260 show it uses 0mA?

You may try a power cycle (disconnecting all power sources after shut down) as it worked for others but this may be a hardware compatibility issue. It is because of this type of scenarios that we recommend contacting the http://www.intel.com/support/oems.htm system manufacturer in order to make sure which wireless adapters are approved to be installed in your system.
