IBM Partnumbers

IBM FRU PN: 39T0497

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 ibm_acpi or 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 the T60, T61 and Z61, the Wireless kill-radio switch disables both WiFi and Bluetooth (Verified on a ThinkPad Z60m, Z61t, T60, and T61).
