[Bluez-users] Modprobe FATAL errors

[Joe Halliwell <joeh@dai.ed.ac.uk>]

Hi,

I've been successfully using blueZ for a month, but (following a kernel
upgrade and reboot -- not wise 3 days before a tech demo...) it's
suddenly stopped working. 

I'm trying to diagnose the problem and have noticed that the kernel is
complaining about the hci_usb module:

Bluetooth: HCI device and connection manager initialized
Bluetooth: HCI socket layer initialized
hci_usb: Unknown symbol hci_free_dev
hci_usb: Unknown symbol hci_alloc_dev
hci_usb: Unknown symbol hci_unregister_dev
hci_usb: Unknown symbol hci_register_dev
hci_usb: Unknown symbol hci_free_dev
hci_usb: Unknown symbol hci_alloc_dev
hci_usb: Unknown symbol hci_unregister_dev
hci_usb: Unknown symbol hci_register_dev
Bluetooth: HCI USB driver ver 2.7
usbcore: registered new driver hci_usb

However, (on my very limited understanding) the HCI layer is functional:

$ sudo hcitool scan

Nevertheless gammu no longer works:

Do the modprobe errors explain this problem? Or is something else at
issue?

I'd greatly appreciate *any* help or advice.
