Bluetooth adapter with partial support for BLE

I've been trying to use Bluetooth on an Android-x86 virtual machine running in QEMU.

So far, I managed to detect the bluetooth adapter and use it to pair with other devices on Android, but Bluetooth Low Energy doesn't seem to work properly, no matter what I do.
Running "hciconfig hci0 lestates"  on the host and the guest machines displays the same output:

Supported link layer states:
	YES Non-connectable Advertising State
	YES Scannable Advertising State
	YES Connectable Advertising State
	YES Directed Advertising State
	YES Passive Scanning State
	YES Active Scanning State
	YES Initiating State/Connection State in Master Role
	YES Connection State in the Slave Role
	YES Non-connectable Advertising State and Passive Scanning State combination
	YES Scannable Advertising State and Passive Scanning State combination
	YES Connectable Advertising State and Passive Scanning State combination
	YES Directed Advertising State and Passive Scanning State combination
	YES Non-connectable Advertising State and Active Scanning State combination
	YES Scannable Advertising State and Active Scanning State combination
	YES Connectable Advertising State and Active Scanning State combination
	YES Directed Advertising State and Active Scanning State combination
	YES Non-connectable Advertising State and Initiating State combination
	YES Scannable Advertising State and Initiating State combination
	YES Non-connectable Advertising State and Master Role combination
	YES Scannable Advertising State and Master Role combination
	YES Non-connectable Advertising State and Slave Role combination
	YES Scannable Advertising State and Slave Role combination
	NO  Passive Scanning State and Initiating State combination
	NO  Active Scanning State and Initiating State combination
	YES Passive Scanning State and Master Role combination
	YES Active Scanning State and Master Role combination
	YES Passive Scanning State and Slave Role combination
	YES Active Scanning State and Slave Role combination
	YES Initiating State and Master Role combination/Master Role and Master Role combination

So now I'm wondering if my bluetooth adapter even supports BLE completely, all the examples i found had all lines with YES.

Running "lsusb | grep Bluetooth" shows:

Bus 001 Device 003: ID 8087:07da Intel Corp. Centrino Bluetooth Wireless Transceiver

Any help is appreciated.
