IBM Integrated Bluetooth III with 56K Modem (BMDC-2)

This is a combination USB Bluetooth and AC'97 Modem Adapter that is installed in a CDC slot.

Features

  • Chipset: CSR BlueCore02 Bluetooth Controller and Conexant SmartV.92 Softmodem DSP
  • Speeds: 434/723 Kbps (Bluetooth 1.1) and 33.6/56.6 Kbps (V.34/V.90/V.92/K56flex)
  • PCI ID: Varies, depends on the AC'97 modem controller's PCI ID
  • USB ID: 1668:2441
  • Headers: One 2-pin connector, one Hirose U.FL connector

Part numbers

  • 93P3471, 91P7319, 27R1880

Linux driver

This card's Bluetooth controller will work with the standard Linux Bluetooth drivers (btusb) with the BlueZ protocol stack. For the built-in softmodem, have a look at the Conexant HSF modem drivers page for more details.

On recent distributions, you can enable/disable the Bluetooth controller with echo 1 > /sys/devices/platform/thinkpad_acpi/bluetooth_enable if you have the thinkpad_acpi kernel module installed. If you don't, use the FnF5 combination instead, as it relies on the embedded controller to work.

Problems

There is an issue regarding connectivity with the built-in softmodem, likely due an outdated K56flex firmware. See Need to disable 56K modem speed for a workaround.
