Hi,

I work with 2.6.10-1.766_FC3 kernel. 
I rebuilt bluetooth.ko and hci_usb.ko using using
those makefile:
---------------------------------
#
# Makefile for bluetooth.ko
#

obj-m	+= bluetooth.o
bluetooth-objs := af_bluetooth.o hci_core.o hci_conn.o
hci_event.o hci_sock.o hci_sysfs.o lib.o

KDIR	:= /lib/modules/$(shell uname -r)/build
PWD	:= $(shell pwd)
default:
	$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
----------------------------------
#
# Makefile for the Linux Bluetooth HCI device drivers.
#

obj-m	:= hci_usb.o

KDIR	:= /lib/modules/$(shell uname -r)/build
PWD	:= $(shell pwd)

default:
	$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
------------------------------------- 


but with this I used bluetooth files of 2.6.8 kernel.
and before building modules I changed in
/lib/modules/2.6.10-1.766_FC3/build/include/net
the bluetooth directory by the 2.6.8 kernel one.

until know everyting is okay and is not blutooth
specific.

The copilation is okay, and I put my too modules in
the specific directories in
/lib/modules/2.6.10-1.766_FC3/kernel

Any bluez module at this time is loaded.
and when I run
#modprobe bluetooth.ko
i can see my module with lsmod.
but when I run
#modprobe hci_usb.ko
I had:

FATAL: Error inserting hci_usb
(/lib/modules/2.6.10-1.766_FC3/kernel/drivers/bluetooth/hci_usb.ko):
Unknown symbol in module, or unknown parameter (see
dmesg)

and I see with dmesg:
Bluetooth: Core ver 2.6
NET: Registered protocol family 31
Bluetooth: HCI device and connection manager
initialized
Bluetooth: HCI socket layer initialized
hci_usb: disagrees about version of symbol
hci_free_dev
hci_usb: Unknown symbol hci_free_dev
hci_usb: disagrees about version of symbol
hci_alloc_dev
hci_usb: Unknown symbol hci_alloc_dev
hci_usb: disagrees about version of symbol
hci_unregister_dev
hci_usb: Unknown symbol hci_unregister_dev
hci_usb: disagrees about version of symbol
hci_register_dev
hci_usb: Unknown symbol hci_register_dev

hci_free_dev,...etc are defined in hci_core.h

bluetooth.ko use hci_core.c and hci_usb.c includes
hci_core.h
and If review what I deed I use thes same version of
Hci_core for my too modulues. 
so I don't undersand why there is a misunderstanding
between the too modules?

regards
