Linux Driver
The Bluetooth adapter uses the hci_usb driver (CONFIG_BT_HCIUSB).
One can enable Bluetooth by pressing FnF5. If this doesn't work, you can load the thinkpad-acpi kernel module and run the following command with root privileges:
# echo "enable" > /proc/acpi/ibm/bluetooth
When Bluetooth is enabled, the Bluetooth-logo LED will light up and executing # lsusb will show an entry mentioning "Broadcom".
On recent ThinkPads the Wireless killswitch disables both WiFi and Bluetooth.
