[gentoo-user] Can't find bluetooth device (BCM2046)

[Mick]

My lsusb shows as much:

Bus 002 Device 004: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of
BCM2046 Bluetooth)

dmesg:

Bluetooth: Core ver 2.15
NET: Registered protocol family 31
Bluetooth: HCI device and connection manager initialized
Bluetooth: HCI socket layer initialized
Bluetooth: L2CAP ver 2.14
Bluetooth: L2CAP socket layer initialized

Bluetooth: BNEP filters: protocol multicast
Bluetooth: SCO (Voice Link) ver 0.6
Bluetooth: SCO socket layer initialized
Bluetooth: RFCOMM TTY layer initialized
Bluetooth: RFCOMM socket layer initialized
Bluetooth: RFCOMM ver 1.11


I've installed bluez and modprobe btusb, because /etc/init.d/bluetooth does
not load it:

Bluetooth: Generic Bluetooth USB driver ver 0.6
usbcore: registered new interface driver btusb

when I run:

$ hcitool dev
Devices:

or

# hciconfig
#

I am not seeing a device there. Is there a particular module in the kernel
that I am missing?

CONFIG_BT=m
CONFIG_BT_L2CAP=m
CONFIG_BT_SCO=m
CONFIG_BT_RFCOMM=m
CONFIG_BT_RFCOMM_TTY=y

I've tried a few more things in the kernel and still nothing, as if there is
no bluetooth device there:

$ hcitool inq
Inquiring ...
Inquiry failed.: No such device

$ hcitool scan
Device is not available: No such device


I read that the above message means that something is blocking the card. That
blocking would not be hardware, because rfkill only shows the wireless card:

# rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no


I tried a Knoppix DVD and it shows an additional device:

The device ID 413c:8156 is the bluetooth which I am not able to find on my
machine.

When running Gentoo there is no such thing ...

Any ideas at all as to what I should be looking for? The devillish thing is
that when I enable bluetooth on my phone it tries to pair with a Dell Wireless
370 Bluetooth Mini-card! What the ... !?
