+HCI BT3C (PC Card) device driver
+CONFIG_BLUEZ_HCIBT3C
+ Bluetooth HCI BT3C (PC Card) driver.
+ This driver provides support for Bluetooth PCMCIA devices with
+ 3Com BT3C interface:
+ 3Com Bluetooth Card (3CRWB6096)
+ HP Bluetooth Card
+
+ The HCI BT3C driver uses external firmware loader program provided in
+ the BlueFW package. For more information, see <http://bluez.sf.net>.
+
+ Say Y here to compile support for HCI BT3C devices into the
