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:

# btsco -v
btsco v0.4c
Error: control open (hw:2): No such file or directory

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