I have purchased Cellink BTA-6030 Class 1 Bluetooth 2.0 + EDR dongles

>Use bluez-firmware and the bcm203x kernel driver for the 2.6 kernels.

How do I use this driver? I have tried to load it with insmod and I get the following:

	EWS4:~/paquetes_rpm # insmod /lib/modules/2.6.4-52-smp/kernel/drivers/bluetooth/bcm203x.ko
	insmod: error inserting '/lib/modules/2.6.4-52-smp/kernel/drivers/bluetooth/bcm203x.ko': -1 Unknown symbol in module

At the same time the following lines appear in the /var/log/messages file:

	Oct 14 12:38:07 EWS4 kernel: bcm203x: Unknown symbol release_firmware
	Oct 14 12:38:07 EWS4 kernel: bcm203x: Unknown symbol request_firmware
