Title:
  USB Bluetooth dongle floods a console (and doesn't work in one
  direction)

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  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

  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.
