Hi all,
I have a Fedora Core 3 box with kernel 2.6.12-1.1372. I have a Logitech bluetooth headset and for my Linux box a USB dongle with a bluetooth chipset from Broadcom Corp.
The bluetooth dongle is working fine and I can see my Logitech headset with hcitool scan. I have compiled the btsco driver in order to use the headset, but the problem comes when I try to insert the snd_bt_sco in the kernel, by doing:
-----------------------------------------------------------------------------------------------------------------
#modprobe snd_bt_sco
FATAL: Error inserting snd_bt_sco (/lib/modules/2.6.12-1.1372_FC3/extra/snd-bt-sco.ko): Unknown symbol in module, or unknown parameter (see dmesg)

This is the output from dmesg:

Any idea about what is wrong ? Maybe my USB dongle does not work with the btsco driver ?
Thanks in advance

You need to build the snd_hwdep kernel module. iirc, it's something like:
make -C /usr/src/linux CONFIG_SND_HWDEP=m modules modules_install
you will also need to get a csr dongle unless you're helping with the
broadcom workaround.

Hi Brad,
Thanks for your quick reply.
When I try to compile the snd_hwdep kernel module with:
---------------------------------------------------------------------------------------------------------------
# make -C /usr/src/kernels/2.6.12-1.1372_FC3-i686/ CONFIG_SND_HWDEP=m
modules modules_install
make: Entering directory `/usr/src/kernels/2.6.12-1.1372_FC3-i686'
CHK include/linux/version.h
CHK include/asm-i386/asm_offsets.h
make[1]: *** There is no rule to build the object `init/main.o',
needed for `init/built-in.o'. Stop.
make: *** [init] Error 2
make: Leaving directory `/usr/src/kernels/2.6.12-1.1372_FC3-i686'
---------------------------------------------------------------------------------------------------------------
As you can see I get that error when trying to build snd_hwdep.
Even though, I can insert snd_hwdep in the kernel by doing:
#modprobe snd_hwdep
After doing this, and having the Bluetooth dongle plugged in and the
bluetooth service started, this is my output of lsmod:

Here is when I try to insert the snd_bt_sco, but it crashes like I
decribed in my previous email.
The enviroment where I am trying to insert snd_bt_sco is correct or do
I need some extra other module, or snd_hwdep must be rebuilt and
inserted again ? In that case any idea about the error that I get when trying
to build snd_hwdep ?
Regarding my bluetooth dongle, I am not trying to workaround any
Broadcom problem, I just want to use my headset :), is then absolutely
necessary that I get a USB dongle with a CSR bluetooth chipset? Which brands
are shipping USB dongles with CSR bluetooth chipsets ?
Thanks a lot
Dani
