from the devices output I see that this device is based on a Silicon
Wave chip and it seems that I don't have this device in my list. So what
kind of model do you have and what is the output of "hciconfig -a".

What are your kernel config settings for the HCI USB driver. I prefer
you try it with these.

	CONFIG_BT_HCIUSB=m
	# CONFIG_BT_USB_SCO is not set
	# CONFIG_BT_USB_ZERO_PACKET is not set

Include a "#define HCI_USB_DEBUG" after the last include directive.

This is a question for the USB guys. Do you have another USB Bluetooth
dongle to test with your notebook?
