Linux driver

This card's Bluetooth controller will work with the standard Linux Bluetooth drivers (btusb). The card's softmodem DSP is similar to the DSP found in theModem Daughter Card (MDC), so the steps to configure the driver is the same as the Modem Daughter Card.

On recent distributions, you can enable/disable the Bluetooth controller withecho 1 > /sys/devices/platform/thinkpad_acpi/bluetooth_enable if you have thethinkpad_acpi kernel module installed. If you don't, use theFnF5 combination instead, as it relies on the embedded controller to work.
