[Bug 386736] [NEW] USB Bluetooth dongle floods a console (and doesn't work in one direction)

[Michał Gołębiowski]

Public bug reported:

I use Hardy. I've recently bought a USB Bluetooth dongle. I can send
files from my phone (Sony Ericsson K800i) to the computer, but not in
the opposite direction. I installed a lot of packages (like obexfs,
gnome-vfs-obexftp, obexfts, obex-data-server etc.) but it didn't help.

So I got used to that I wouldn't be able to copy files to my mobile in
Hardy. But there is another problem - I discovered that when my adapter
is connected and the bluetooth service started (/etc/init.d/bluetooth
start) my console is flooded in amazing speed by this text:

(...)
[ 1533.116617] hci_scodata_packet: hci0 SCO packet for unknown connection handle 92
[ 1533.117589] hci_scodata_packet: hci0 SCO packet for unknown connection handle 92
[ 1533.118542] hci_scodata_packet: hci0 SCO packet for unknown connection handle 92
[ 1533.125639] hci_scodata_packet: hci0 SCO packet for unknown connection handle 92
(...)

I've read that this can be fixed by some simple kernel modifications. As written here (in Polish):
http://ftp.coolmax.one.pl/linux/repository/pkg/DRVs/BlueTooth/Flood%20komunikat%F3w%20SCO%20podczas%20u%3Fywania%20Bluetootha.html
this can be fixed by checking the device address via lsusb (at mine:
$ lsusb
(...)
Bus 001 Device 004: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
(...)
) and adding the following line:
{ USB_DEVICE(0x0a12, 0x0001), .driver_info = HCI_BROKEN_ISOC },
to the drivers/bluetooth/hci_usb.c file, after a comment:
/* RTX Telecom based adapters with buggy SCO support */
or similar.

If there's any simpler fix, I'll be grateful to hear about it.
